3. 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. Calibrator battery power could only used for roughly 15

times. Please change the battery when the red light becomes dark, indicating low battery.

4. Length adjustment and Calibration:

4.1 Adjustment of sensor length

Aluminum tube at the bottom can be shorten according to different requirements from customers.

Steps are as follows:

4.1.1 Customer specifies the sensor length according to the needs;

4.1.2 Cut the unwanted part with steel saw;

4.1.3 Remove the burrs and the debris at the cutting area with knife file to avoid short circuit;

4.1.4 Remove the plug, and assemble the rubber plug in the aluminum tube, then assemble the plastic bottom plug.

4.2 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; The purpose is to define the position level of the fuel when it is full and empty in the tank. The electrical signal changes as the fuel level changes, calculating the height of the fuel level.

Note:

4.2.1Calibration of full level

Fill the tank to desired full level, put sensor into the tank, wait for about 30 seconds until the aluminum tube of the sensor is filled with fuel, then press and hold on to the "F" button on the calibrator for 5 seconds till the green LED light slowly flickers. This indicates that calibration for full level is in progress. Release the "F" button at this moment. The green LED light will turn off in about 10 seconds, indicating that the calibration of the full level is complete.

4.2.2 Calibration of the empty level

Remove sensor from the container/tank. Place on the side. After liquid fully drains from the sensor, press and hold on to the “E" button for about 5 seconds until the green LED light starts to flicker fast. This indicates that calibration for empty level is in progress. Release the "E" button at this moment. The green LED light will turn off after about 10 seconds, indicating that calibration of the empty level is complete.

4.2.3 Calibration completion

Disconnect the calibrator after calibration is done. Connect red cable and black cable with power, calibration becomes effective when sensor is power on.

Note:

1. If press the wrong button during operation, you can switch off the calibrator and exit the mode and readjust.

2. Please ensure the calibrator is turned on at all times during calibration. Re-calibrate the sensor if power off/switch off.

4.2.4 Inspection

When calibration of the full level and empty level is done, inspect the output signal of the sensor:

(RS232/RS485 output needs special equipment or connect with GPS tracker to inspect the signal output.)

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 re-calibrate it. 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.


3.Notice

1. For the signal transmission line, especially the one of RS232,communications circuits should not be too long, and should use the shielded wire.

2. For the sensors of the signal RS232/ RS485, when debugging the failure of communication, you can exchange the white line and the blue one and test again. If it works then, it is the connection error before. The operation is only for digital communications.

3. The power supply voltage of sensor cannot be more than the normal working voltage, and the consumption.


Exclusion and solutions

2 Test 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.

remark

1 it usually can be functional while executing the 2.2.2 process

2 it usually occur on 0~5V signal

3 4~20mA output supply voltage DC20~28V,current is 4~20mA except communication output

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