Pulse counter functionality enables the FMB devices to count digital impulses going to DIN1/DIN2. This means that 2 digital inputs of the FMB devices can now be used for precise fuel flow meter data reading. Impulse based fuel usage monitoring is much more accurate than a different type of fuel metering sensors and it makes the FMB devices a perfect solution for high fuel usage machines like cranes, construction vehicles, mining machines, agriculture equipment.

FMB devices have pulse counter capability out of the box from firmware 03.25.05.Rev.00 and later.

Use case:

Pulse counter functionality enables the FMB devices to count digital impulses going to DIN1/DIN2. This means that 2 digital inputs of the FMB devices can now be used for precise fuel flow meter data reading. Impulse based fuel usage monitoring is much more accurate than a different type of fuel metering sensors and it makes the FMB devices a perfect solution for high fuel usage machines like cranes, construction vehicles, mining machines, agriculture equipment.

How does it work?

When pulse counter I/O is enabled, then Pulse Counter DIN1/DIN2 will count every DIN1/DIN2 state change to HIGH and send the counted number with the next record. Pulse counter value is reset after sending the record.
