Please make sure that the installation area does not obstruct the installation of the stainless steel hose
clamp.
4.1.4. Test
Draw an area at the bottom of the fuel tank corresponding to the area available to installation at the
top. Wash this area by removing all the grease, dirt and sands on the surface and dry it with a rag.
If the conditions allow it, please read the fuel level from the fuel gauge in the cab or observe the
depth of the fuel by opening up the fuel tank cap. Otherwise, please knock at the side of the fuel tank
with hand and assess the current depth of fuel by the sound. For example, there is still 45cm fuel in
the tank with a height of 50cm, as the installation requires almost full capacity of fuel in the tank.
Then as shown in Figure 8, please push the couplant onto the detector and stick the detector to the
selected area to find the precise location for installation. During this process, please observe
whether the reading in the LED digital tube display approximates 45cm, or 450, and the signal
value is not bigger than 0.0.2.
Figure 8. Couplant
The difference between the fuel level (unit: mm) and the signal value is that the latter has decimal
points as shown in Figure 9.
