DFM general information and technical specifications / Purpose of use and application area

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

Terminal unit gathers, registers, stores received signals and transfers them to telematic

Server. Software installed on the

Route

control

(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.
