2.3.7 Adaptation of indications for specific conditions of exploitation
To adapt indications of the selected
) for specific conditions of
operation, you may use the following features of the Fuel Tank Monitor application
(see figure 17):
1) Thermal correction
function (
Settings
, submenu,
Sensor
tab) is recommended to
activate for automatic compensation of the fuel thermal expansion/contraction.
ATTENTION:
Thermal expansion/contraction of the fuel caused by the temperature
deviation, alters the volume of fuel in the tank. As consequence, the sensor transmits
a significant increase or decrease of fuel level to Android device.
Automatic thermal compensation is disabled by default. To activate it, press
button in the
Temperature correction
area and move the blue contact slider to the right in the window of
settings that is opened. Insert the required coefficient value into the field
Coefficient

.
To turn off the thermal compensation, insert the coefficient value
0.0
or shift the blue slider to
the left

during 24 hours follow the
requirements:
- Vehicle is not moving with engine off.
- Ambient temperature should correspond to normal operating conditions of the
- Tank should be filled with fuel not less than 10 % of the total fuel volume.
- There should be the same fuel volume in the tank (refueling or draining is not allowed).
2)
The
Remaining distance of the route
function (
Settings
submenu,
Sensor
tab) is used
to define automatically the remaining distance for this Vehicle, in accordance with the
measured volume of fuel in the tank and the value of the average fuel consumption specified.
To configure this function, specify the necessary value of the average fuel consumption in the
Average consumption
field.
