Unique Features
Introduction
The level sensor enjoy multi-innovation technologies, with capacitance as the sensitive element, GB sensor series continuous detects the height of the fuel level with less than 1mm resolution. Sensor length can
also be shorter to fit tanks with different heights. GB sensor can replace the original fuel level sensor on vehicles and connects with oil gauge. With wide range of voltage input, it has no limitation to input voltage.

Tips on calibaration:
1. Calibrator:
Calibrator must couple with the sensor, and it has 12V/ 23A battery inside.
Red light is the power light. If the light isn't on when switch on, battery replacement is needed;
Green light is the calibration light. Full/ Empty button is showed in above picture.
Note: Calibration is necessary before using the sensor due to different fuel types;
2. Length adjustment and Calibrator:
2.1 Adjustment of sensor length
Aluminum tube at the bottom can be shorter according to different requirements from customers. Steps are as follows:
2.1.1 Customer specifies the sensor length according to the needs;
2.1.2 Cut the unwanted part with steel saw;
2.1.3 Get rid of the burrs and the debris at the cutting area with blade or a
screwdriver to avoid short circuit.
2.1.4 Take down the filter unit, take out the plug, and assemble the plug in the aluminum tube, then assemble the filter.
3. Calibration of the fuel level sensor
Calibration of the fuel sensor is calibration of the full level and empty level. The fundamental principle is to record a full value and empty value in the fuel sensor when tank is full and empty; defining the positions of fuel is full and empty in the tank. The electrical signal changes as the fuel level changes, calculating the height of the fuel level.
Note: when the fuel sensor becomes shorter, it shall be recalibrated. Calibration to empty level and full level is related to the medium and the fuel level, instead of volume of the tank, so this operation can be operated in room (make a container, full filled with diesel,simulation of the tank). Calibration of full level shall go first, then the empty level, or else, it is impossible for the sensor to enter thesetting mode.
4. Calibration of full level
Full fill the tank, put sensor into the tank, wait for about 30s till the aluminum tube of the sensor is full of fuel, then press the “full” button on the calibrator for 5 seconds till the green LED light slowly flickers, it indicates that calibration enters full level mode. The green LED light is off after about 10 seconds and it indicates that the calibration of the full level is OK.
5. Calibration of the empty level
Take the sensor out of the tank; put it outside of the tank. When all the fuel flows out of the sensor, press the “empty” button for 5 seconds till the green LED light flickers fast, it indicates that calibration enters empty level mode. The green LED light is off after about 10 seconds and it indicates that the calibration of empty level is OK.
6. Calibration completion
Disconnect the calibrator after calibration is done. Connect Pin 1 and Pin 3 on sensor with power, calibration becomes effective when sensor is power on.
Note: If press the wrong button during operation, you can switch off the calibrator and exit the mode and readjust.
7. Inspection
When calibration of the full level and empty level is done, inspect the output signal of the sensor:
Full level: V out is 5V
1/2 level: V out is 2.5V;
Empty level: V out is 0V.
If the output signal meets the values listed above, it means calibration is OK and normal operation of the sensor. Otherwise, please check the mode of connection and recalibrate it.
After Sale Service Of Sensor
Our Company
1.When need to use calibrator ?
After you cut it ,if you never cut it ,no need calibrate .
2.How to calibrate it ?
Press the full or empty button till the lamp flash one time ,release the button wait 5 seconds ,
then finish calibration . (for type FLS-700 sensor)
3. Can I use it with gps tracker?
Yes, it support any gps tracker with 0-5V analogue input or RS232 input or RS485 input . If RS232 interface, the gps tracker need to do integration with our sensor protocol.
4. Which is the gps tracker list it support?
Any gps tracker with 0- 5V analogue input and RS232 input and RS485 input.
5. What is the resolution?
0.1mm. If multiple with section area, we can conclude the liter resolution,
normally less than 1 liter for vehicle tank.
6. Can we measure the liter changing with it?
Yes, create one map between level and liter, then can draw liter changing.
7. Why is it expensive than other floating sensor?
Because capacitance is more stable and higher resolution than floating sensor.
So do not compare with different type of sensor. Just compare with other capacitance sensor,
our will be the most cost-effective one.
8. Do you have support for integration with our application?
Yes, we have EE and SW engineers team to support for you with integration of our product.
9. Is it safe for using with gasoline?
Sure, we have ExtdIIT certification.
10. Can we cut short to adopt our tank?
No, it does not support user cutting short. We have another model ULS-700 support customer resizing.
