Compact Electromagnetic Flowmeter MAGMAX EGM2300C


*Specifications are subject to change without prior notice.

MAGMAX EGM2300C is a compact electromagnetic flowmeter which is a combination of EGS2000 flange type primary head and EGC300 high performance, reliable converter. Polypropylene lining tube and hard rubber lining tube are available and nominal sizes from 25 to 1000 mm are lined up.
EGM2300C offers improved Flow noise rejection and useful Self-diagnosis function such as various monitorings.
EGM2300C is most suitable for precise measurement of potable water, sewage, hot water, etc.
* MAGMAX® is registered trademark of the TOKYO KEISO CO.,LTD.


  • · For the size from 25 to 100 mm, polypropylene lining which is heat resistant and durable is available.Therefore the flowmeter can be used for potable water, sewage, and hot water up to 90°C.
  • · Hastelloy® C electrode provided as standard.
  • · High accuracy of ±0.5% of reading.
  • · High speed data processing for quick response. Suitable for batch process control and pulsating flow.
  • · Field current frequency can be adjusted up to twice of power frequency, which is effective for slurry noise rejection.
  • · Self-diagnosis function such as empty detection, conductivity monitoring, electrode status monitoring and analog output monitoring is provided.
  • · Easily visible, blue dot matrix LCD indicator offers flexible indication by 1, 2 or 3 lines.
  • · Quick set-up function for easy data setting/change such as scale range, pulse rate, etc.
  • · All setting parameter can be set/changed by an Infrared touch sensor without opening the housing cover.
  • · High pulse frequency output up to 10 kHz is achieved: this meter can be used for short time batch process control.
  • · Pulse output, bi-directional flow measurement, double ranges, status output, control input, etc. are provided as standard.
