Sealing of sensor
To protect the sensor from unauthorized interference you should install two seals. The first
seal prevents the measuring head from twisting and the second one is set on a detachable
connection of interface and connecting cables.
For sealing of the measuring head (look pic. 8.12):
make a wire loop;
tightly wrap the hermetic input;
make a twist of wire and thread the wire through the hole of the screw ES.004;
place the ends of the wire in the seal (using СИЛТЕК seal ends of the wire should go
through the holes of the seal on the side opposite to marking);
Select the wire slack and snap the seal.

For additional mechanical fixation of the seal we recommend to drag it to hermetic output and
press with a plastic electro technical clamp tie.
9. Calibration
To ensure the most accurate control of fuel level, tank calibration is performed - initially empty
(full) tank is filled (merged) by equal portions of fuel and with the help of special software "eS
Install" the sensors statements are measured and fixed after adding (pluming) of each portion.
Portion sizes should be chosen depending on configuration of a tank: if horizontal cross-
sectional area of the tank in height is sharply changing the portion should be the less. (For
example, the recommended portion for a 500 l tank of КамАЗ should be 10 l).
You must also take into account the time of level balancing level in tanks of complex
configuration (for example, in 2-tank systems) due the fuel flow.
Requirements to a measuring cup or a flow meter that provides a measurement of portions are
shown in Table 4.
