Guarantees UNINTERRUPTED OPERATION of the system
–
the most reliable option.
IMPORTANT NOTE: This connection scheme may be used for sensors with an aluminium as well as with a
carbon plastic body.
NOTE: The system uses a power supply converter with galvanically isolated inputs and outputs. The
parameters of the supply must be selected having regard to the technical specifications listed in the ratings
sheets of the sensor, of the monitoring terminal or of any other applicable devices, adding a 20% reserve.
Sensor supply voltage: 10

Converter
NOTE: The fuse FA must be installed as close as possible to the supply power connection point in order to
protect the onboard network from short-circuits in the power supply of the fuel consumption monitoring
system.
NOTE: Points
