Fuel Level Sensors at a glance

Fuel Level Sensors at a glance

In the previous dispatches we have learned why it is so important to monitor fuel, as well as the main methods of fuel monitoring from Technoton company.

 

A fuel level sensor (or FLS) is installed into a fuel tank. It usually works as a part of telematics system and serves to determine level of fuel in the tank and transfers this data to user's computer via GPS tracker.

 

Nowadays the market offers a number of different FLS types, which differ in the principle of operation.


5 MAIN TYPES OF FUEL LEVEL SENSORS

Float fuel level sensor

 

Detects resistance depending on float position.
+ cheap;
+ usually already installed by the manufacturer;
- inaccurate;
- fuel fluctuations dependent;
- noise affected output signal.

 

Ultrasonic Fuel level sensor

 

Transmits ultrasonic pulses toward fuel tank bottom. Reflected ultrasonic waves are received by the sensor and converted into output interface.
+ for any type of liquids;
- inaccurate, needs "ideal" maintenance conditions;
- complicated installation process.

Pressure fuel level sensor

 

Detects pressure inside of the fuel tank and converts it into output interface.
+ for any type of liquids;
- not applicable for mobile units;
- expensive;
- highly affected by environmental pressure changes.

 

Dipstick fuel measurement

 

Detects height of fuel in the tank visually. Fuel volume can be calculated mathematically based on fuel tank dimensions.

 

+ AT LEAST SOMETHING 😉

Capacitive fuel level sensor

 

Detects change of capacitance due to the influence of fuel in between measuring electrodes. Electronics determines changes of capacitance in the form of output interface.
+ highly accurate;
+ can be used on any fuel tank (mobile/stationary);
+ value for money;
- can be used for non conductive liquids only.
