| Analog signal supports local two - wire touching calibration Digital signal RS485 supports automatic computer calibration | For the calibration of differe nt media, only two key "zero" and "full Span" can be easily achieved | Easy operation and suitable for many kinds of liquid measurement |
| Customs high temperation with cooling device | allowing media temperatures of up to 300°C. | special for high temperation application |
| It can be used with GSM/GPRS/GPS module | Remote vehicles monitoring | Reduce fuel consumption operation costs prevent oil theft |
| With different kinds of oil | Diesel, gasoline vehicles are available | strong universality |
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)
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..

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.
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
Sensor jammed
autoadaptation uncomplete
Sensor fault
4 oil level flow
service voltage abnormal

Sensor fault
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
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
