The DM4000 is a highly accurate digital process indicator, available in three versions:

DM4000U: For common industrial sensors.
DM4000C: For various types of pulse input, to provide RATE and TOTALISE functions.
DM4000A: A dedicated flow computer for analogue inputs, also providing RATE and TOTALISE functions.

The sensor type and range are user configurable, either from the front panel or via the optional serial communications port. All ranges are fully calibrated which means the user can change quickly and easily from one sensor type to another. The re-transmission can be any part of the incoming range, allowing the DM4000 to be used as a smart sensor transmitter.

Two output slots are provided which can accept a variety of option cards, including relays, current re-transmission and Sensor excitation supply.
