M930 Battery Powered Electromagnetic Flow Meter

Electromagnetic flow meter for applications in remote or hard-to-reach areas with battery life time up to 10 years. Coil power draw limits maximum diameter to 300mm or 12 inches.

  • Battery life time up to 10 years
  • Capacitive buttons and remote control - USB (Modbus)
  • Datalogger, empty pipe detection, self-diagnostic

M930 Battery Operated 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 USB with Modbus protocol. Ex930 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.). M930 can detect empty pipe and prevent counting invalid data.

Typical applications

Battery powered M930 is designed for are where reliable power supply is not available. Typical applications are irrigation, dewatering, construction sites, waterworks maintenance or waste-water maintenance.
