GPS tracker Fuel Level Sensor for Vehicle 

1. Introduction:


Ultrasonic liquid level gauge/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.


2. Application:

Ultrasonic liquid level meter ULM-1000 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 are provided through the tank bottom so no damage and drilling of the tank are needed.

The measured data could be:
1. Saved in the internal memory which capacity is enough for 1 month autonomic work
2. Sent via a transceiver such as GPRS modem or GPS/ GPRS tracker in real time.


Using ULM-1000 fuel level meter 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

Check fuel changes:



1. To maintain the equipment in a dry environment, humid environment tends to damage the internal circuitry.
2. Do not put a dusty environment.
3. Do not put too hot or cold places.
4. Do not use in severe vibration equipment.
5. Please use a dry cloth to clean, do not use chemicals and detergents.
6. Do not paint the device, which may lead to internal circuit.
7. Do not disassemble the device.
8.Please read the manual carefully before usingto avoid damage to devices.
