M921 Precision Electromagnetic Flow Meter

Quick Overview

The M921 is designed to measure, indicate and record the instantaneous and total flow of the conductive media flowing past the sensor. The flow meter has no moving parts in the flow profile and can be used with any conductive liquid, even in extremely dirty flows containing solid materials. The flow meter will record both forward and reverse flows. The M921 is equipped with 6, user configurable, standard isolated outputs: 4-20mA either active or passive, frequency output, impulse output, status output (with relay), RS485 and USB/RS232 output. The additional features include temperature measurements, pipe and electronics self diagnostics, a RS485 Modbus output, improved operating ranges and accuracy of 0.25%. The unit covers pipe diameters of 15 - 800mm with hard rubber or PTFE linings. Options available for 12vDC, 24vDC, 48vDC and mains power supplies.

The M921 is an updated version of the MAG920 electromagnetic flow meter.

Details

M921 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. Ex921 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.

M921 Upgrades

M921 is similar to MAG920 in terms of 0.25% accuracy, empty pipe and electronics diagnostic, liquid temperature measurement through excitation coils, I/O ports, datalogger and other functions. Thanks to modernized design, the M921 is now much easier to operate and maintain. It has 6 buttons, large dot-matrix display, customizable screen elements, easy-to-use clamp opening mechanism and more mounting options. Datalogger memory increased by factor of 60.

Applications

  • Chemical Industry
  • Pharmaceutical Industry
  • Food Industry
  • paper Industry
  • Water Industry
  • Waste-water/ Sewage Industry.


The M921 flow meter is designed for measuring, indicating and storing flow and volume data of conductive liquids. The MAG920 flow meter records both positive and negative flow. As there are neither moving nor mechanical parts in the flow profile, the device can be applied to measure extremely polluted liquids containing even solid pollution. The only limitation is that the device can be used solely with conductive liquids.

The M921 flow meter is equipped with six isolated outputs and one isolated input as standard. Digital outputs (frequency, pulse and relays) and input is user configurable. Current output 4-20mA can be used as passive or active type. Communication with the unit is available via RS232 and RS485 outputs with Modbus protocols. Temperature measurement can be read on display, via Modbus or used for alarm purposes. The internal logger can record up to 900,000 readings with a programmable sample rate.

Please note, the product builder includes the standard options only. Earthing rings (required for certain pipe materials) and optional ANSI & DIN 11851 Flanges and higher pressure ratings available on request.
