2.2 Calibration

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)

1.self-calibration: put the sensor slowly into the The tested medium while power on, let the liquid get into the feed inlet slowly ,stoping when the liquid is overflew the vent hole of the sensor. and this operation accomplish the calibration of the sensor . In order to prevent the failure of the calibration process , please do this process for at least 2 times .( notice:This way is under the condition of powering on , outage restart will restore the factory Settings.In the condition of empty fuel tank,refueling to full, the sensor itself are also able to complete the self-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)

remote automatic calibration :if adopting RS232 or RS485 for data transmission, it can be accomplished the calibration by vehicle GPS location system sending orders. Sensor has two orders of calibration ,D1,D2. When the fuel tank empty , it will send D1, and when the fuel tank is full, it will send D2, and this operation could accomplish the remote calibration.

2.3 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.

3.Notice

1.Only one signal can exist among RS232/ RS485/ 0-5V/ 4~20mA, and you can use either one of them. The trunk of RS485 can meet multiple sensors at the same time, but you should set the address of each sensor in advance. Address of each sensor must be unique, in case the trunk is locked. RS485 trunk is made of half-duplex chips, so when it reading data, you should set aside the corresponding time for the module. The reading speed cannot be too fast: when it reads continuously, the time interval between the two instructions cannot be less than five seconds.

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

3. 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.

4. The power supply voltage of sensor cannot be more than the normal working voltage, and the power consumption of the sensor’s power supply cannot be less than the normal working power consumption.

5. The actual environment should conform to the requirements of the basic parameters of sensors, and shall not exceed the normal range, or it would damage the sensor, even cause other accidents.

6. On account of oil products, there are differences between the mediums of the calibration and use, users had better operate according to 2.2.2.

7. Do not remove sensors or damage it maliciously, or we do not guarantee it.

8.General factory accessories include Flange, rubber blanket, O-Rings, booklet of instruction, certificate of conformity. If you have special needs, please tell us in advance.

9.Guarantee period of the sensor is one year. All accessories including rubber blanket, O-Rings, are beyond the scope of “ threeguarantees ”.

Symptom of failure

1No-output /communication error

2The output value unchanged

3Measurement error of output value

4Output value floats up or down

remark
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

3 service voltage abnormal
