2.3.6 Calibration of fuel tank
Fuel Tank Monitor app recalculates the measured value of fuel level into the fuel volume in the
tank according to the calibration table. To set up calibration table it is required to carry out
calibration of fuel tank
.
Calibration procedure is a sequence of fuel fillings by fixed portions from empty to full state of
the fuel tank (see video
IMPORTANT:
To measure the volume of fuel portions it is necessary to use
measuring reservoir with inaccuracy not more than 0.25 %.
To make fuel tank calibration correctly, where the sensor is installed, it is required to follow
the procedure:
•
should not be loaded and stand on the flat horizontal surface;
•
fuel tank should be empty;
•
the vehicle wheels must be of standard size;
•
the tire pressure should match with the prescribed for this Vehicle;
•
the vehicle should not move, ignition off, engine off;
•
pause between fuel fillings by portions into the tank should be not less than
60 seconds.
Tank calibration table is stored in memory of
specific
Android device using Fuel Tank Monitor
app (
Settings
submenu,
Tank
tab) (see figure 15).
