2.3.5 Calibration of the measuring system
The calibration
of the measuring system is necessary for correct displaying of the fuel level
measurement readings by a
specific
Android device.
IMPORTANT:
In case of replacing old Android device, it is necessary to copy profile of
particular sensor into memory of new Android device (see
) or repeat the
measuring system calibration operation.
In the process of the measuring system calibration, minimum and maximum possible levels of
fuel measurement in tank are stored into the memory of Android device in
Sensor calibration
bar of the Fuel Tank Monitor application (
Settings
submenu,
Sensor
tab)
(see figure 13).

Measuring system calibration with Fuel Tank Monitor application
For the measuring system calibration make the following steps:
1)
Select the desired sensor from the list of available devices (see
).
2)
Get the sensor out of the fuel tank and wait for (30…60) seconds so that all fuel run
off the probe.
3)
Measure sensor probe length L (mm) from ending of tubes to draining hole
(see figure 14) and enter the measured value in
Fuel Level Sensor Length After Cutting
field (see figure 13).
