| 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. | | Pulse counter functionality enables the FMB devices to count digital impulses going to DIN1/DIN2.
