N08 Fuel Sensor Car Mobile DVR Installation Fuel Level Gauge Sensor for Vehicle MDVR

1.N08 Introduction:

N08 series fuel sensor is independent research and development by Nancetech, which within innovative technologies. It can detect fuel level continuously. And The resolution is less than 1mm. JT606 can be cut the length to fit the height of fuel tank .Simply flanged installation that no need extra screws. Wide voltage input to make sure no voltage limits under any situation.

Features:

 1)It can be cut according to the height of fuel tank.

2)Integrated structure without any elastic elements, also support various signal output.

3)Push-button field calibration, it’s very convenient.

4)Wide Power voltage input.

3.3 Wiring Definition:

4.1 Cut fuel sensor:

4.1.1 The measurement of fuel tank height

4.1.2Clear Metal Crumbs

After cut the fuel sensor，It’s necessary to clear the metal crumbs in the bottom of the fuel sensor.

4.2 Calibration

   Calibration is to do full or empty tank calibration. The basic priciple is that define the point for full& empty tank and

record a value respectively. When fuel level was changing, the fuel sensor would generate corrsponding signal change

then figure out the height of the fuel level.

Note:

Every time,If you cut the fuel sensor,You must recalibrate it. The calibration is related to medium detected and the liquid

height, having nothting to do with capcity. So the calibration can be done indoor.

The way to recalibrate the fuel sensor:

1) Press the button in fuel sensor

2) the configuration program

Calibration Circumstances:

1)On scence

2)Indoor (Make a container, fill diesel to simulate as a fuel tank)

We mainly introduce the calibration mode through button at present, full calibration should be prior to empty calibration.The fuel sensor should be powered on normally before calibration.

Note: 

For this type of fuel sensor, It must be done full calibration firstly, and then empty calibration. Otherwise It’ s necessary to recalibrate fuel sensor again.

4.2.1 Calibration through button

Remove the top lip of fuel sensor by tool, see picture below.

Instruction about the button.

4.2.2Full calibration

Step: fill the full tank, then insert the fuel sensor,wait about 1 minute.

4.2.3 Empty Calibration

Note:

For this type of fuel sensor, It must be done full calibration firstly, and then empty calibration. Otherwise It ’s

necessary to recalibrate fuel sensor again.

Step: Plug out the fuel sensor and place it outside of the fuel tank, wait about 2 minutes  then do the empty calibration

after one minute
