M920 Precision Electromagnetic Flow Meter

Top of the range electromagnetic flow meter with 0.25% accuracy, wider flow range, Modbus protocol, temperature measurement and many other functionality improvements.

  • 0.25% accuracy, wider flow range
  • Empty pipe detection, temperature measurement
  • Datalogger, dosing, self-diagnostic
  • 7 different I/O interfaces + Modbus protocol
  • Spanish included

M920 Precision Electromagnetic Flow Meter accurately measures flow of conductive liquids from 5 µS up. As there are no moving parts in the flow profile the flow meter can be applied to measure extremely polluted liquids containing even solid pollution. Evaluation and readout unit (transmitter) indicates both positive and negative flow as well as total and custom volume counters. Logged data can be shown on display or downloaded via RS232 or RS485 with Modbus protocol. Ex920 sensor for use in potentially explosive atmospheres in category II 3G EEx nA II T5/T6 is available in remote version of the flow meter.

Model-specific features

Configuration data are backed up continuously and can be recovered when necessary (battery replacement, power failure due to severe electrostatic discharge, etc.). M920 can detect empty pipe and prevent counting invalid data. As the only flow meter in range, the M920 can measure liquid temperature through excitation coils. Three digital outputs (frequency, pulse and relays), 4-20 mA current loop and one digital input come as standard.

Typical applications

M920 with its high accuracy is ideal for critical applications in chemical, pharmaceutical or food industry. Providing wide range of outputs, the M920 can be used in other areas such as paper, water, waste-water, etc.
