FMB devices have pulse counter capability out of the box from firmware 03.28.07.Rev.03 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.
Specification:
| Model | DIN1 Max frequency, Hz | DIN2 Max frequency, Hz | Input Voltage threshold (DIN1) | Input Voltage threshold (DIN2) | ||
|---|---|---|---|---|---|---|
| 2000 | - | 7.5V | - | |||
| FMB110 | 50 | 2000 | 7.5V | 2.5V |
|
|
| FMB125 | 50 | - | 7.5V | - |
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.
