RS485 bus can also meet DuoGe sensor, but prior to set each sensor address, each sensor address must be the only, in case the bus locked. RS485 bus USES is half-duplex chip, so read data should be set aside time to module response, read the speed can not be too fast, read for two orders of time interval between not less than 200 ms.

3,Calibration process

Sensor adopts the technology of the microcomputer, without calibration can be applied directly to all kinds of weak corrosive liquid measurement

4,Sensor installation

1. If the old car is to be removed the original sensor; New car installed directly.

2. Before installation, please check the attachment: flange, rubber pad, o-rings, whether is complete and screw

3. Will O type in the root of the sensor trap

4. Rubber pad and flange constructed and the fuel tank to good hole a flange,;and the screw good, should be tightened in turn symmetrical strength, to ensure that each direction stress even, avoid oil leak.

5. The sensors with a wrench into tighten can complete the installation of the sensor

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.

 

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 

 

 

Symptom of failure

1No-output /communication error

2The output value unchanged

3Measurement error of output value

4Output value floats up or down

 

cause analysis

1 Open circuit of the power or voltage too low

Sensor fault

Wrong connection of the lines and wires

2 service voltage abnormal

external interference

Sensor jammed

Sensor fault

3 service voltage abnormal

external interference

 

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

 

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
