MVD/Pulses converter

The MVD/PULSES CONVERTER device is an electronic device installed on CNG methane dispensers which on one side reads the MVD registers installed on the Micro Motion sensor CNG50 and containing the mass and volume of fluid circulated in the sensor, on the other hand it supplies the impulsive signals to the counting head installed on the measuring assembly.
