Fuel level translation is carried out in accordance with calibration table. To create the table, it
is necessary to calibrate the fuel tank. This procedure is a sequence of fixed refueling portions
from empty to full tank. During calibration, the value of DUT-E output signal is established
depending on fuel amount in a particular tank (see DUT-E fuel level sensor installation video
for details).
DUT-E can be used in combination with recording and display units (including GPS/GLONASS
Vehicle Tracking devices), and their input signal specifications have to be compatible with
DUT-E output signal specification according to Clauses 1.4.2 — 1.4.5.
When using DUT-E AF/A5/A10/F/I fuel level sensors, calculation of fuel amount is carried out in
a registration unit such as a GPS Tracking device or on the server using vehicle monitoring
system software.
DUT-E 232/485/CAN fuel level sensors can calculate current fuel amount independently in
accordance with calibration table recorded in the sensor internal memory with Service DUT-E
software.
