Figure 9. Fuel Level and Signal Value
Note:
Sometimes, the gauged liquid depth is 000mm and the signal strength is 000 when the vehicle is
stationary. In this situation, fill the fuel to more than 80% of the full capacity and start the vehicle
engine, if the correct depth can be obtained with the signal strength ranging from 1 to 2 by shaking
the vehicle, then we can judge the location is suitable for installation.
After finding the suitable installation location, a circle mark of the detector will be left on the
couplant when taking off the detector gently in the vertical direction. Then draw a square frame
tangent to the circle with the small Phillips screwdriver and mark the location of the detector as
shown in Figure 10.

4.1.5. Finish the Installation
Clean the couplant on the fuel tank and the detector with a rag. Remove the paint on the surface of
the fuel tank within the square frame with the sand paper. Then clean the dirt and grease on the
surface with a rag. Make sure the contact surface is clean. But don't remove the paint outside the
square frame.
Fasten the stainless steel hose clamp to the installation location and leave room for plastic cable ties
