DFM
are mounted into fuel supply line of the vehicle engine. DFM measure actual (instant)
fuel consumption rate and generates an output signal to forward it to a vehicle tracking
device (see figure 3 a)
.
Terminal unit gathers, registers, stores received signals and transfers them to telematic
Server. Software installed on the
Server
generates
Analytical reports
, which allow time-

control and
Vehicle
fuel consumption monitoring via web-browser
(
see Figure 4
).
DFM with pulse output
interface
provide data on actual fuel consumption of engine
(overall fuel consumption and average instant fuel consumption)
DFM with digital output interface
provide real-time control over extended set of infor-
mation:
instant fuel consumption;
engine operation time – overall and in different engine operation modes;
fuel consumption – overall and in different engine operation modes;
voltage in on-board power network;
total operation time of flow meter and duration of power-supply from embedded
battery;
flow meter’s malfunctions;
evidence of interference to flow meter’s operation.
