Ultrasonic fuel level measurement for fuel consumption control fuel tank level sensor  



Ultrasonic fuellevel meter is used for fuel level measurement in vehicle fuel tanks in order to control fuel consumption. 

The measurements are realized by the ultrasonic radiator installed directly on the external bottom part of the fuel tank and data processing box. 

The ultrasonic fuel level meter can measure levels of diesel and petrol or other liquid materials depending on software settings.


ULM-0.8 measures changing level of any liquid (diesel, gasoline, water, liquefied gas, milk etc.) in moving and fixed tanks (vehicles fuel tanks, fuel tank tracks, railway tank cars, industrial tanks and liquid storages). 

The measurement is provided through the tank bottom so no damage and drilling of the tank are needed. 

The measured data could be: 

•saved in the internal memory which capacity is enough for 1 month autonomic work 

•sent via a transceiver such as GPRS modem or GPS/ GPRS tracker in real time.

Using ULM-0.8,  you can get the following important information: 

-Fuel level and amount in the tank

-Amount of dispensed fuel

-Fuel consumption rate

-Theft detection

-Operational and statistical reports
