Series DPW Digital Paddlewheel

1% FS, Flow and Optional Temperature Readings, Programmable Output

The SERIES DPW Digital Paddlewheel is an economical choice for applications where liquid flow measurement is desired. This Series offers two programmable totalizers via the optional LCD and RS-232/RS-485 interface, two optically isolated flow pulse outputs, and selectable 0 to 5 VDC or 4 to 20 mA flow outputs (optional temperature).

Product Applications

  • Liquid monitoring
  • Chemical proportioning or batching
  • Laboratory equipment
