'''FMB''' devices have pulse counter capability out of the box from firmware [[FMB firmware errata#03.25.05.Rev.00|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.[[File:Pulse_counter.gif|center|]]Specification
Maximum supported frequency is 50Hz.
Maximum value 2147483647.
High level:
Input Voltage threshold (DIN1) 7.5V
Input Voltage threshold (DIN2) 2.5V
