This fuel monitoring system supported by fuel level sensor CLS2 , which is a capacitance type of high precision.
During the fuel consumption monitoring system, the accuracy is 0.5% and the resolution is 1mm, Voltage type, Current type and Digital type are available.

2)Our whole Fuel consumption Monitoring system, includes 3 parts:

1. Fuel level sensor: Our capacitance fuel sensor with high accuracy 0.5%, in addition, it can be cut according to the depth of fuel tank, we can provide different types of fuel sensor: Digital, analog, voltage, the resolution is 1mm.

2. Hardware: Our GP series can monitor fuel sensors for detecting fuel consumption.

3. Fuel consumption system Software: Data will be displayed as curve real time. The manager can download the history data from the server as analysis report and curve with speed and mileage also supporting the report of analysis output by PDF. Excel format, from which you can clearly know where the fuel expended, under what conditions, if there is someone steel the fuel or not, all of the information will be displayed in a simple way.

3) CLS2 smart capacitance Fuel Tank Level Sensor are designed for liquid level measurements where the levels are lower than 3 meter, 316 stainless steel allows the transmitters to be suitable for harsh environments and various measuring medium, such as oil, fuels, or other media compatible with 316 stainless steel.The user can realize the ZERO or RANGE self-calibration with two buttons or two lead lines to meet different requirements on various complex occasions.



This sensor adopt high-speed MCU of CNC technology, adopting self-calibration

Calculation , and leaves out the complicated Manual calibration while using. in normal

circumstance, the sensor can directly be used in the measurement of the diesel, if need to calibration, you can use the three following ways to complete. (each can work)


CLS2 Capacitor motor oil level sensor combined capacitor sensor and liquid level sensor.The product not only contain the features of high precision measurement and maintenance-free, at the same time it doesn't influenced by temperature and medium.It can be automatically measuring error caused by different temperature or medium for precise compensation,achieving the purpose of accurate measurement.


The entire sensor machine doesn't contain any elasticity or moving parts.Impact resistance, maintenance-free, long service life, easy installation,can be installed in various occasions.Accurate measure for gasoline, diesel oil, hydraulic oil level and other various weak corrosive liquid level



This liquid level sensor is level measuring instrument,contain high resolution ratio and measurement accuracy.It is automatic calibration which does not need manual intervention,no temperature drift, and is not affected by medium change.In other words,regardless of the measured medium is water or gas or diesel, no matter how temperature changes, it can output signal accurate liquid level height at one sensor. Completely solve the problem of measure medium difficulty ,like ethanol and methanol,and the problem of measurement error caused by oil’s label and great temperature difference in different areas.


The equipment can be used cooperatively with GPS vehicle positioning terminal and other terminal to make vehicle positioning and fuel consumption management system.It can evaluate the usage of the vehicle and the driver's driving level,monitor gas up situation of vehicle,precise calculate hundred kilometers fuel consumption,completely eradicate the phenomenon of oil stolen,oil spilling,detouring,make extra money,private use of government vehicles,falsely making receive..

strong universality



6)  definition of the output line

Interface output line use 6 core cable, connecting definition

     Installation Notes

Before installation, please check the attachment: Flange, rubber blanket,O-rings, and Whether the screw is consistent and complete

Trape the o-rings to the root of the sensor ( packed prior to shipment )

Daub the Oil-resistant sealant on the two side of the rubber pad, and aim flange plate to the tank flange hole,then fixed by screw,symmetrical tighten the strength in turn to make sure uniform stress and avoid oil spilling.

To finish the installation ,insert the sensor and use a wrench to tight.

connect the power cord, communication line, cable, ground wire according to the definition, and yellow line and green line need to trape one by one , preventing from the short circuit

Link the power of the sensor after checking the circuit

Installation position should be placed as near as possible to the center of the fuel tank, in order to reduce the influence of the oil level of tilt and the oil level of volatility while on the hill.



Symptom of failure

1No-output /communication error

2The output value unchanged

3Measurement error of output value

4Output value floats up or down


Exclusion and solutions

1test connect→test if the voltage is greater than 10V when load→test the supply current [range 3~10mA] → connect method see 2.1,or change over blue and white line[digital communication only]→if all above is regular or current beyond normal range,the sensor occurred failure.

2Test the supply voltage when load[ex.voltage unstable] → recharge the sensor →test if there is a serious interference around→test whether sensors hole is blockage from top to bottom → execute 2.2.2→If not,the sensor occurred failure.

3 detect whether service voltage is stable while loading ( if the voltage is unstable) → →whether external have interference→check whether the sensor is jammed → execute the 2.2.2 process →then it should be the sensor fault

4 check the oil leve is stable → check the service is normal and functional →whether external have interference →execute the 2.2.2 process→then it should be the sensor fault


Waterproof IP68 CLS2 GPS Fuel Tank Level Sensor Cut Length Sensor 0.5-4.5V



1 4~20mA output supply voltage DC20~28V,current is 4~20mA except communication output

2Check the tank oil level is float or not,if become regular after recharge,check the interference and the power

3 it usually can be functional while executing the 2.2.2 process

4 it usually occur on 0~5V signal





The ultrasonic fuel level sensor is used for digital recording vehicle refueling, to prevent driver stealing oil , avoid the waste of resources, improve operational efficiency, and improve the traffic safety, strengthen the operation and management level.

       This sensor is applicable to various types of vehicles such as trailers, taxis, buses, concrete mixer truck, engineering machinery, sanitation trucks and other.
