This Product is adopted by non-contact measurement of ultrasonic sensor technology, which is researched and developed by our company and it is initiated in China. It is also widely used in fuel consumption project and all products were sold abroad.
2. Product introduction
2.2 Working principle
Max Power Consumption
-40℃ ~+85℃ (Technical Grade)
It depends on the material and thickness of the vessel.
The range is about 5~100cm for 5mm steel plate.
≤0.8kg or 0.8MPa
Accuracy of Liquid Measurement
Providing analog voltage output,RS232 and RS485
Range of voltage: 0~5V, 0~3V, 1~5V,
1~3V.Actual liquid height and voltage output are in proportion Maximum
Output Voltage: V;
Input Liquid Height: H;
Measurement Length: L;
H=(V - VMIN)/(VMAX-VMIN)*L.
2.4Features of Product
1. High accuracy.
Resolution of sensor’s measurement for fuel height is 0.1mm.And its measurement accuracy is ±0.5%. It keeps higher accuracy even in highest or coldest outside environment.
2. Excellent stability.
Different from direct-contact measurement of float-type, pressure-type, magnetic sliding-type, fuel level sensor uses ultrasonic and non-contact measurement, which can avoid pollution and corrosion from fuel and keep stability in a long period of time.
3. Easy installment and maintenance. You only need to install the sensor probe on lower surface of fuel tank. You don’t need to change its original measurement system or punch hole for it. Its original fuel meter operates as usual.
4. No pollution and lower consumption. This non-contact measurement and non-punch hole for fuel tank can keep off pollution from fuel.
5. High reliability. It can still work in bad environment and it is damp-proof, acid-proof, flame-retardant, anti-interference, intellectualized. This product can be used independently to check data from auxiliary display. It can also use with GPS, which sends data to background for statistics, analysisand query.
This ultrasonic fuel level sensor can be used for all kinds of vehicle(logistics car/taxi/public bus/passenger bus ) .It records refueling and fuel consumption in a digital way, which avoid fuel being stolen, wasting and enhance the efficiency, improved safety and reinforce management.
