Flow Compact Electromagnetic FlowmeterMAGMAX® EGM4050C

Compact Electromagnetic Flowmeter MAGMAX<sup>®</sup> EGM4050C


*Specifications are subject to change without prior notice.

The MAGMAX® EGM4050C is a compact electromagnetic flowmeter consisting of the flange type EGS4000 primary head, which is lined with PFA or PTFE, from the proven MAGMAX® series, and the EGC050 converter mounted on it.
The enhanced self-diagnosis unit can detect empty flow and monitor the status of the primary head.
Nominal sizes of 10mm to 1000mm are available. The EGM4050C is ideal for chemicals and many other applications.

  • · High-quality, clear PFA reinforced with a punched plate ensures high resistance against corrosion, erosion, and permeation (applicable size: 25 to 150mm)
  • · PFA, PTFE, and other lining materials are available
  • · High accuracy of ±0.5% of reading
  • · High-speed data processing enables quick response. Suitable for controlling batch processes and measuring pulsating flows.
  • · The extendable excitation system can handle applications with severe fluid noise such as slurry.
  • · The LCD with backlight provides various indications in 1–3 lines.
  • · The quick setup function makes it easy to handle changes in the flow range, pulse rate, etc. The attached magnet can be used to change the settings without opening the cover of the converter.
  • · 10kHz high-speed pulse output. Capable of handling short batch processes
