Product Details

fuel level sensor


This CLS series of sensors is a metrology-grade measuring instrument with high resolution and measurement accuracy. It does not require manual intervention, is automatically calibrated, has no temperature drift, and is unaffected by changes in the medium. In other words, the same sensor, regardless of the temperature of the medium being measured, whether it is water or gasoline or diesel, correctly outputs the accurate level signal. The problem of difficult measurement of mediums such as ethanol gasoline and methanol fuel has been completely solved, and the measurement error caused by different oil labels and large differences in temperature has been solved at the same time. At present, the technology is unique in China and is at the international advanced level.

Fuel sensor installation method:

1, If it is an old car, the original sensor needs to be removed. The new car is installed directly;

2, Please check the accessories before installation: flange, rubber pad, O-ring, whether the screws are complete and consistent;

3, Place the O-ring on the root of the sensor;

4, Apply oil-resistant sealant to both sides of the rubber mat, and then fix the hole position with the flange and the fuel tank flange, and fix it with screws. When tightening, symmetrical rotation should be applied to ensure uniform force in all directions and avoid oil leakage. 

5, Insert the sensor into the wrench and tighten the wrench to complete the sensor installation.

6, Connect the power cable and communication cable separately according to the definition;

7, Check the line is normal, you can turn on the sensor power, the sensor can work normally.

When need cut length, need calibration.

Manual calibration :

at the time of empty fuel tank, put the yellow line short circuit with the ground wire( black line) , and then power on the sensor, operating for 60s or longer, after that , disconnect the back ground wire and the yellow line , and this operation could accomplish the calibration ( notice: Sensor already setted to 0 # diesel prior to shipment ,without Special Circumstances)
