Flow transmitter

Block diagram

Overview

Our integrated circuits and reference designs enable you to build flow transmitters with sensors that convert flow measurement into an electrical representation. Transmission occurs over a loop-powered 4-20 mA interface, an IO-Link interface or wireless connection.

Design requirements

Flow transmitter designs often require:

  • Precision signal chain for sensing.
  • Multi-protocol industrial communication and interface solutions.
