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.

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

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
