Fuel Sensor Tutorial

What Is Fuel Sensor

Fuel sensor is a device designed to make accurate measurements of fuel level in vehicle tanks. According to these measurements a GPS tracking and telematics platform features the following data:

  • fuel level in the tank of a vehicle
  • fuel consumption per time period
  • average fuel consumption. e.g. miles per gallon (mpg)
  • fuel refills or drains

Application

Fuel sensors are used on stationary units, such as fuel tanks at gas stations, and on vehicles: cars, locomotives, ships, etc.

Types of Fuel Sensors

The most common types of fuel sensors are:

  • Factory-installed sensors
    • Float fuel sensor
  • Additionally Installed sensors
    • Capacitive fuel sensor
    • Ultrasonic sensor

Floating fuel sensor is a factory installed sensor. It is used to display a relative fuel level on the vehicle’s dashboard. However, such fuel sensors show only an approximate level of fuel in a tank and are not very accurate; its relative error reaches up to 10-30%.

Capacitive and Ultrasonic fuel sensors are considered to be high-precision instruments in fleet management systems. Such sensors are installed additionally by the integrators of GPS tracking and telematics systems. The relative error of these sensors is much less – 1-2%.

Float fuel sensor

A float fuel sensor is installed into the tank of a vehicle at the factory.

Float fuel sensor

Operation concept: а float is connected to the potentiometer. When the fuel level changes, the float also changes its position. It causes a resistance change, and therefore a change of an output voltage of the sensor. The floating sensor transmits this data to a vehicle’s dashboard by:

  • a separate wire, analog signal (in the older vehicles)
  • CAN bus, digital signal (in the modern vehicles)

Capacitive Fuel Sensor

Some fleet owners install a Capacitive Sensor in order to monitor fuel consumption and fuel drains.

Capacitive fuel sensor design concept

Operation concept: Capacitive Fuel Sensor is an actual electric capacitor.

How does it work? The measuring system consists of 2 non-contacting tubes, where one of the tubes is inserted into the other one. They act as capacitor plates. Both tubes are connected to the sensor from one end and are open from the other and are electrified.

When the tubes are placed into a vehicle tank, the fuel fills the tubes and the space between them. The fuel in this case becomes the dielectric of an electric capacitor. As the fuel fills the space between the tubes, its electrical capacitance changes.

Gasoline has a lower electrical resistance than air. That is why the recharge will take less time. So the more fuel there is in the tubes, the faster the capacitor will be charged.

The sensor measures the height of fuel column in the tank and in the fuel sensor itself due to the time spent to charge the capacitor. These parameters are sent to the GPS tracker and then all the data including geolocation are transmitted to the GPS tracking platform.

Ultrasonic Fuel Sensor

Ultrasonic Fuel Sensor

Some fleet operators choose to install ultrasonic fuel sensors to monitor fuel consumption and fuel drains.

Operation concept: Ultrasonic sensor has a wire connection with a GPS tracker and works as an ultrasonic transmitter.

This transmitter, which is fixed on the outside wall of a fuel tank, at the bottom, sends ultrasonic impulses. The signal travels from the bottom up to the fuel surface and back. The reflected signal will be received by the same transmitter. Based on the time of flight it measures the height of the fuel column in the tank.

These parameters are sent to the GPS tracker and further to the GPS tracking platform alongside geolocation and other valuable data.

However, this technology has a few pitfalls. First of all, the installation process proved to be a very difficult one and shall consider a lot of factors.

  • A special epoxy glue or a metal band is used to connect the sensor to the bottom of the tank. Make sure the sensor adheres perfectly to the tank surface, otherwise ultrasonic signals will be distorted and the measurements will be inaccurate.
  • Should the tank have any baffles (to control the rapid flow of fuel and prevent its sloshing), it may affect the signal and the measurements. This makes choosing the right spot for the sensor even more difficult and is often done in a hit-and-miss fashion.
  • The echo signal can be distorted or lost if the tank shape is too complex. Besides, blisters and pits on the internal surface of the tank can also affect the quality of the measurements. As the result – a greater error.
  • Dirt and water (which turns into ice in winter) accumulate at the bottom of the tank. Again, it distorts the ultrasonic beam and causes false fluctuations in the fuel level readings.

In real-world terms, Ultrasonic fuel sensors are only used for vehicles running on gas, as there are no other options available.

How to choose the right fuel sensor

To select capacitive and ultrasonic fuel sensor one needs to know:

  • tank dimensions (primarily the height)
  • outputs to connect with the tracker

Tank dimensions

Tank height and shape play a crucial role for capacitive fuel sensors. Make sure the client provides this data (at least approximately) before the installation.

The measuring part of the sensor must be slightly bigger than the tank height (to make sure the sensor reaches fuel at the bottom of the tank). During installation the measuring tubes will be cut to fit the tank. However, it is important to leave a gap of 1-1.5 inches (3-4 cm) between the sensor and the bottom to prevent a short circuit due to dirt and water accumulated at the tank bottom.

Tank dimensions

Different manufacturers of fuel sensors can offer different size ranges, however in most cars a sensor of 0.7 m (∼27.6 inch) will be enough.

Multiple sensors on one vehicle

One might need to consider a few fuel sensors for one vehicle, if it falls into one of the following cases:

  • The vehicle has two or more fuel tanks. Generally, a heavy-duty vehicle (a truck or an off-road vehicle) will have two or more fuel tanks. Installing a fuel sensor on each tank will provide a full picture of the fuel level. In a GPS tracking system it can be displayed separately for each sensor and as an aggregate value of all the fuel sensors.
  • The fuel tank of the vehicle has a complex shape. As it’s often the case with agricultural equipment, a fuel tank might have a customized shape or consist of two different sections. In this case it requires two (or more) fuel sensors to provide for precise measurements. The GPS tracking and telematics system will show an average value of all the fuel sensors.

Fuel tankers have 2 or 3 tanks, each of them having at least 3 sections. For maximum accuracy each tank and each section should be equipped with a fuel level sensor. Make sure, that the sensor has an RS-485 output. An RS-232 won’t provide for multiple sensors to be connected to one tracker.

  • The fuel tank of the vehicle is extra long. Such tanks can be usually found on campers or trains. In this case, as you can imagine, even minor fluctuations in the tank will affect the sensor readings. Using two sensors and installing them diagonally at the opposite sides will help to eliminate the problem. The GPS tracking system will show an average value of the both fuel sensors. Extra long tanks (long and only 4-6”/ 10-15 cm high) are often used in cars. In this case it might be most efficient to consider fuel level monitoring via CAN-data.
Multiple sensors on one vehicle

Fuel Sensor Outputs

If your client’s vehicle is already equipped with a tracker, job one will be to ask for the tracker’s make and type. Once you’ve cleared that up, go to Navixy Devices to check available outputs for the tracker and to select the fuel sensor that fits. If the tracker supports both analog and digital signals (just like Teltonika FMB 125), fuel sensor with digital interface (e.g. RS-485) should be favored.

If a client needs both a fuel sensor and a tracker, we would definitely recommend a digital interface (e.g. RS-485) in both cases.

Fuel sensor: installation routine

In 100% of cases clients choose to hire professional tech crews instead of installing fuel sensors themselves.

To get the sensor up and running it takes:

  • 2 technicians
  • Installation tools
    • Bi-metal hole saw
    • Corner drill
    • Metal drills (look for HSS-TiN drills)
    • Flat head and Phillips head screwdriver
    • Pliers
    • Hack saw or tube cutter
    • Riveter (to fix the sensor to the thick-walled tank)
  • Calibration set
    • Calibration tube
    • Portable gas station – required during tank calibration for precise measurement of fuel level
    • Tanks for temporary fuel storage (often inflatable/ collapsible fuel tanks)
  • Consumables – U-bolts, corrugated tubes, etc.
  • Laptop – to calibrate the sensor and the fuel tank
  • USB Connector kit (to connect the sensor and the laptop). Usually sensor manufacturers make their own USB adapters (e.g. UNU-USB by Omnicomm) to fit the sensors.
Fuel sensor: installation routine

Quite often technical crews operate an all-in-one mobile calibration station, which has everything from tanks to drain the fuel to a refilling station on one vehicle.

All-in-one mobile calibration station

And last but not least, installation of fuel sensors requires knowledge, skill and expertise to deal with all kinds of tanks…and situations.

Now let’s have a closer look at installation processes for each fuel sensor type.

Installation of Ultrasonic Fuel Sensors

Tank external surface should be polished at the bottom area, where the sensor will go. Then the sensor must be glued to the tank and fixed with a metal band, wrapped around the tank. Afterwards the sensor is connected to the power supply and calibrated.

Now let’s take it step by step:

  1. Before you start with ultrasonic fuel sensor installation, the first thing to do will be to find the geometric center of the tank bottom.
    For rectangular tank bottom the geometric center can be found by drawing the diagonals.
  2. Tank bottom shall be ground to metal at the spot the sensor will be attached to.
  3. Apply glue on the sensor. (make sure the glue is included in the supply package!)
  4. Press the glued sensor hard to the tank and fasten it with a metal band, wrapped around the tank.
  5. Connect the sensor to the dashboard and to the laptop using a special adapter. Download the software for sensor calibration.
  6. Calibrate the tank.
  7. Disconnect the sensor from the laptop and connect it to the tracker.

The installation will take approximately 4 hours.

Installation of Capacitive fuel sensors

Installation of a capacitive fuel sensor begins with removing the tank and residual fuel in it. For the next step cut a hole to fit the sensor and screw it to the tank. Connect the sensor to the power supply, calibrate the sensor and the tank.

Now let’s put each step under a microscope.

  1. Before the installation, drain fuel from the tank and remove fuel vapors. This step is very important! Don’t skip it, otherwise sparks from drilling the opening will cause an explosion, especially in petroleum vehicles. Fill the tank with water and steam it.
  2. Define the geometric center of the tank.
  3. Drill an opening at the geometric center. Warning: take precautions to prevent metal chips from getting inside the tank.
  4. Measure the depth of the tank. The tubes shouldn’t touch the bottom of the tank for fuel to easily get inside the sensor. A hacksaw or a tube cutter will help you adjust the length of the sensor.
  5. Connect the sensor to the dashboard and the laptop using a special adapter. Download the software for sensor calibration.
  6. Calibrate the sensor. The fuel sensor needs to adapt to its new length. Put the sensor upside down (with measuring tubes facing up) and fill it with fuel. Keep the fuel for 1-2 minutes and drain it.
  7. Install the sensor, so the measuring tubes will be inside the tank, while the electronics + PCB and cables – outside the tank.
  8. Fasten the sensor using self-tapping screws
  9. Calibrate the tank
  10. Disconnect the sensor from the laptop and connect it to the tracker.

The installation will take approximately 4 hours. For more information watch OMNICOMM installation training video (10 min).

Connection to the CAN bus

CAN bus is a twisted pair (two wires twisted around each other). To find the CAN bus in your vehicle, refer to the wiring diagrams, otherwise it will be impossible to find it in the mish-mash of car wires.

Once it is located, you can connect to it via a CAN Crocodile contactless reader (recommended) or connect to it directly (less recommended).

Connection to the CAN bus
  1. Find out the vehicle brand, model and year of manufacture before connecting to its CAN bus.
  2. Check the vehicle manuals to make sure that the CAN bus monitors fuel level data. Unless it does, the other steps will make no sense.
  3. Go to the tracker manufacturer’s website to select a CAN module brand that fits.
  4. Choose the CAN module type/model based on your vehicle or heavy equipment type.
    For instance, Teltonika requires different CAN module for cars (LV-CAN 200) and for trucks (ALLCAN 300).
  5. Ask the CAN module vendor to supply a connection diagram for your vehicle brand, model and year of manufacture. Usually it takes not more than 30 min to find the right diagram.
  6. Connect the CAN module the way it is shown in the diagram.
  7. Use a a mini-USB to USB cable to connect the CAN module to the dashboard and the laptop with pre-downloaded setup software.
  8. Insert the number given in the diagram to set up the CAN module.
  9. Disconnect the CAN module from the laptop and connect it to the GPS tracker.
  10. Perform a lite tank calibration.

The installation will take approximately 30 minutes (considering the diagram is available).

Sample wiring diagram

Fuel Sensor Outputs

As of 2018, the most common outputs to connect to GPS trackers were:

  • For factory installed trackers:
    • analogue output
    • CAN interface
  • For additionally installed trackers:
    • analogue output
    • frequency output
    • digital output:
      • RS-232
      • RS-485
      • CAN-2 interface
      • Bluetooth radio interface
      • Other radio interface

Analogue Signal

Equipment: Fuel sensor with analogue output, GPS tracker with analogue input

Specifications: in this case fuel level data is transmitted to the GPS tracker as voltage (potential difference between the sensor output and the ground, DC). The higher the fuel level, the higher the potential difference is.

For instance, 1V stands for an empty tank, 10V stands for a full tank. A tank calibration is required to convert the volts into litres or gallons.

Fuel sensor with analogue output, GPS tracker with analogue input

GPS trackers will transmit the values to the GPS tracking system in volts (e.g. 6.35 V).

Advantages: you can use a cheap and simple GPS tracker with basic outputs only.

Disadvantages: readings accuracy is affected by voltage fluctuations, wiring condition and age, as well as other factors contributing to error.

Application: you can recommend analogue fuel sensors if your clients’ GPS trackers have no digital inputs (analogue inputs only) or if the client is looking for a cheapest solution.

Frequency Signal

Equipment: fuel sensor with frequency output, GPS tracker with frequency input (e.g. BCE Blue).

Specifications: in this case fuel level data is transmitted to the GPS tracker as an impulse frequency (for instance, in the range from 30 Hz to 2000 Hz). The higher the fuel level, the higher the frequency is.

For instance, 30 Hz stands for an empty tank, 2000 Hz stands for a full tank. A tank calibration is required to convert frequency into litres or gallons.

Data modulation technique works just like the well-known FM radio. In this case an analogue sensor acts as an AM-radio, where the signal is amplitude modulated (More on amplitude modulation here). Frequency modulation for fuel level sensors emerged after analogue modulation but before digital signals. It is more resistant to noise than the analogue signal, but not as noise-free as digital signals, and is basically not used anymore.

Advantages: less error than in analogue signals. Frequency signals are quite often used as auxiliary ones for analogue sensors. In this case they are called frequency-analog sensors.

Disadvantages: cost-effective GPS trackers rarely have frequency signal options

Advantages: fuel sensors with frequency signals are much less widespread than analogue or digital solutions. However, you can recommend these sensors to your clients if the other options are not available.

Digital Signals

Equipment: Fuel sensor with digital output RS-232 or RS-485, GPS tracker with RS-232 or RS-485 digital inputs.

Specifications: fuel level data is transmitted as digital signals (conventional numbers without units of measurement) over the copper wires. A GPS tracking platform will get these readings as positive integers, usually the 2byte characters from 0 to 65535. A tank calibration is required to convert the numbers into litres or gallons.

Advantages: ultimate noise immunity during signal transmission (compared to analogue signals). It also provides more accurate readings than analogue fuel sensors. Ability to connect more than one sensor on one tracker (through RS-485 interface, RS-232 allows to connect only one sensor). Check the GPS tracker manufacturer’s website to see the number of fuel sensors to be connected via RS-485.

Disadvantages: GPS trackers with digital signals are usually more pricey than similar trackers without digital inputs.

Application: If a client wants to monitor fuel level for their vehicles, then a digital interface should be a go-to solution. Make sure you consider whether the GPS tracker has RS-232 or RS-485 input.

CAN Bus

Equipment: CAN module for CAN data reading, CAN module-compatible GPS tracker or OBD2 GPS tracker supporting OBD data reading.

Specifications: the GPS tracker will use fuel level data from the factory-installed fuel sensor. These readings will be transmitted as a % of the total tank volume. A lite tank calibration is required to convert % into gallons or litres.

Advantages: fast non invasive installation or DIY installation in case of OBD2 tracker. No extra money spent on sensor setup.

Disadvantages: less accurate than a capacitive sensor. Some vehicles (usually the older ones) don’t transmit fuel level data via a CAN bus.

Application: feel free to recommend this option if it is impossible to install a capacitive fuel sensor on the vehicle. Don’t forget to check if the vehicle’s CAN bus does transmit this data.

Bluetooth

Equipment: Bluetooth fuel sensor, GPS tracker with Bluetooth connectivity, compatible with the fuel sensor. For instance ESCORT TD-BLE

Specifications: fuel level data is transmitted as digital signals over the wireless bluetooth channel. A tank calibration is required to convert the characters into gallons or litres.

Advantages: wireless sensors require easy and cheaper installation. The latest models have no wires at all, not even for the power supply. They are already equipped with a battery for the whole life span of the device thanks to Bluetooth Low Energy (BLE). Some say that wireless fuel sensors are the future.

Disadvantages: every wireless fuel sensor manufacturer has their own data transmission protocol (a unified or simply a market-leader protocol is not yet acquired). Thus every GPS tracker manufacturer should consider compatibility with fuel sensors of every make. Besides, as any emerging technology, the wireless options cost more than their wired alternatives.

Application: if the client’s GPS tracker has a Bluetooth connection, then a wireless fuel sensor can be the right choice.

Fuel Sensor Design: Unorthodox Solutions

Many fuel sensor manufacturers provide their devices with additional features. Some of them can be quite cutting-edge and useful.

Remote power monitoring

If a fuel sensor suddenly goes offline, the first thing to do will be to check if it is connected to any power supply. Some sensors, e.g. manufactured by Siensor, allow for remote power monitoring. These fuel sensors have one extra wire connected to an analogue or discrete input of the tracker. Add a new discrete or measuring sensor on the platform and stay aware.

Fuel temperature monitoring

Do your clients really need fuel temperature monitoring on a daily basis? Hard to say. Yet it’s good to know it’s there by default. That’s why some sensors manufacturers (TechnoKom, for instance) provide this option.

Universal outputs

Modern fuel sensors can be powered with both analogue and digital outputs. It’s a great solution for the customers who already have GPS trackers on board. Sometimes clients don’t know what inputs are already taken, so it’s good to have an alternative. Universal fuel sensors are provided by a few manufacturers, for example, Escort.

Fuel level indicator

Fuel level indicator is installed directly in the driver’s cabin to show the exact fuel sensor reading. It works both ways: managers will always see the fuel level and the drivers will always know the fuel is being constantly monitored (any fuel thieves will be caught red-handed). Below you can find a fuel indicator by Omnicomm.

Fuel level indicator

Bent tube design

Should the fuel tank have a complex shape, the sensor tubes can be bent with the help of a bending machine (one bend only, not exceeding 70 degrees). The option is provided by a few manufacturers.

CANlike bus/ S6 Interface

Technoton, a world-famous Belarus-based manufacturer, promotes the idea of a single interface for factory-installed and additional sensors (including fuel sensors). Technoton offers CAN 2.0 for this purpose. Their fuel and other sensors are connected to the vehicle CAN bus, just like factory-installed devices, to transmit the fuel level data.

This approach yields a few benefits. Mainly it removes any limitations on the number of devices to be connected to one tracker. However, fuel sensors operating on CAN interface will cost more compared to similar solutions with other outputs. That’s why this technology hasn’t become widespread.

Explosion-proof version

Some Safety rules and regulations require fuel sensors to be explosion-proof (e.g. if the sensor is installed inside fuel tankers). These sensors have a specific design to provide enhanced explosion and fire safety confirmed with a test certificate.

GPS tracker meets Fuel sensor

In 2016 some fuel manufacturers came up with the idea to install a GPS tracking module on a fuel sensor directly (like in DUT-E GSM by Technoton). So if your clients only need to track and trace the location and to monitor the fuel level, then they will need to install just one single device, which is a big plus. However it limits (but doesn’t eliminate completely) any other devices to be connected to such a tracker+sensor set. Besides, any compound solution is always a compromise, which will take its toll on the commonly used GPS tracking features.

Fuel Sensor Calibration

After the sensor tubes are cut, the device requires to reset its max and min values. The process entails taking measurements at an empty tank and the full tank (when the sensor tubes are fully submerged in fuel).

To do so, many choose to use a tube tank, however it can be done without any additional paraphernalia. The former is considered to be more favourable as in this case the sensor tubes will be covered in fuel from the outside as well. But the latter is definitely easier: no need to drag along a bulky (and stinky!) piece of equipment. The difference in results will be subtle, however some device integrators insist on the tube-tank approach.

Sensor Calibration without additional accessories

  1. Connect the fuel sensor to the laptop, with the sensor head facing down and the sensor tubes facing up
  2. Fill the tubes with fuel (simply pour it down inside the tube)
  3. Once the fuel level stands still, assign this value in the configuration software as the new max value for the fuel sensor.
  4. Drain the fuel to make sure no residues remain inside the tubes
  5. Once the fuel level stands still, assign this value in the configuration software as the new min value for the fuel sensor.

Sensor Calibration using a tube tank

A tube tank is basically a plastic pipe about 700 mm long, approx. ID – 50 mm. It must be closed and sealed at one end. Sometimes fuel sensor manufacturers use the plastic pipe as a packing for the sensor and supply them together. Here’s a sensor calibration broken into steps:

  1. Put the plastic pipe upside down, with its open end facing up. Securely fix the pipe.
  2. Fill the pipe with fuel
  3. Connect the sensor to the laptop and put the sensor into fuel.
  4. Once the fuel level stands still, assign this value in the configuration software as the new max value for the fuel sensor.
  5. Take the sensor out of the plastic pipe
  6. Once the fuel level stands still, assign this value in the configuration software as the new min value for the fuel sensor.

Fuel Tank Calibration

Tank Calibration is required to convert fuel readings in digital signals or volts into gallons or litres.

Full tank calibration

All calibration practices follow more or less the same routine:

  1. Pour an accurately measured volume of fuel inside the tank. It’s called a pass. Each pass should be at least 1/10 to 1/20 (more recommended) of the total tank volume, e.g. 20 litres. This way the calibration table will have from 10 to 20 (more recommended) entries.There are many techniques that installation crews may apply to accurately measure fuel volume for one pass. For instance, transfer pumps with meters or portioning at the fuelling station.
  2. Check the value on the laptop. Make an entry to the calibration table as follows: sensor value – number of litres/ gallons.
  3. Make another pass and another entry to the table. Repeat until the tank is full.
  4. If the tank has a complex shape, the pass volume should be divided by two when reaching the “crooked” spot.
  5. Add the entries from the calibration table to the GPS tracking platform (Go to Devices and settings => Sensors and buttons => Add measurement sensor). Some sensors support the option of uploading tank calibration tables from a file (e.g. Fuel sensors by Omnicomm). Otherwise it should be added manually.
Adding a fuel sensor/ tank calibration table on Navixy

Lite tank calibration

If you use CAN data for fuel monitoring or if the fuel tank is up to 22 gallons/ 100 litres (as the case might be for some vehicles), a lite calibration will be enough. In this case the calibration table will have two entries only:

Sensor Value
Quantity
00
100Tank capacity in litres/gallons. E.g. 65 litres/ 12 gallons

Fuel Monitoring on Navixy

Remote monitoring on GPS tracking platform Navixy can be set in a few clicks. Go to Devices and settings => Sensors and buttons => Add measurement sensor and add the tank calibration table.

In some cases the measuring sensor will be added on the platform automatically. For instance, when installing an OBD2 GPS tracker.

Widgets

Fuel and OBD2&CAN widgets on Navixy will provide real-time data on the fuel level.

Fuel monitoring in OBD2 and CAN widget on Navixy

Notifications

Navixy GPS tracking platform can instantly notify about any refills and drains of fuel. Set the rule for Fuel level change in Alerts and keep tabs on any critical changes:

Notification alerts for fuel level change on Navixy

Enable notifications:

  • by SMS
  • by email
  • by push notifications in X-GPS Monitor app

or upgrade it to emergency notifications to make sure it won’t slip unnoticed.

Fuel reports

For in-depth fuel level analysis a fuel report can be the optimal tool. Select if the X-axis should show time (in times, hours or even seconds) or mileage (miles or kilometers driven).

Navixy fuel report

Reports can also feature advanced options:

  • Show speed
  • Show ignitions
  • Smooth graphs – this tool automatically smooths fuel fluctuations by giving the average values. The state-of-the-art fuel sensors have already deployed this algorithm.
  • Ignore peaks – enable this tool to eliminate false refills and drains. The system will hide any refills/ drains of the same volume if they were made within 30 min.

All in all, the fuel reports can give metrics on:

  • Number and volume of refills
  • Number and volume of drains
  • Absolute fuel consumptions – number of litres consumed during the time period
  • Relative consumption (GPM – gallons per minute, MPG – miles per gallon, litres/100 km, l/h – litres per hour)

Keep in mind: for instant data monitoring in Tracking, the fuel consumption will not be based on the fuel sensor readings, but on the average fuel consumption for the car make and model instead (in MPG or litres/100 km).

Leading fuel sensor manufacturers

Fuel sensor manufacturing (as any other telematics sensors manufacturing) is a very painstaking but profitable process. Fuel sensors are produced by:

  • Sensors and meters manufacturers, e.g. Siensor, Escort, etc.
  • GPS tracker manufacturers – in this case a fuel sensor is a side or additional product. Some GPS tracker manufacturers purchase sensors by other make and brand them as theirs.

Currently the most popular fuel sensor developers and manufacturers are:
