Interface & Data

Data Outputs:

    Isolated 4-20 mA output – fully configurable, invertible
    0-1000 Hz Pulse output – fully configurable, invertible

Data logging:

    date/time stamped flow rate and flow total data in FAT32 file format, easily imported into Excel. Configurable to trigger on time interval (1-999,999 sec), rate and/or total set-point values. Store up to 191,800 log events in the memory buffer, downloadable to flash memory via USB port.

External Communications:

      Computer connection via optional Communications Modules:
      Industrial Ethernet/IP
      Modbus RTU
      Modbus TCP
      Profinet RT/IO
      Profibus DPV1

Process Control:

      Two independently configurable Form C relays. Load capacity: 30V, 100mA max (ext. supplied)

Configure to flow rate

        for high/low/range rate alarm. Programmable release values enable auto release or manual batching operation.

Configure to flow total

      for automatically triggered, timed batch operations for proportional feed applications.
