EFM-LDG-W Electromagentic Flowmeters for Water and Waste Water

$1,385.00$5,485.00 exc GST


The EFM-LDG series of flowmeters is accurate and we have versions for many applications and different flow rates. Call us to talk about your particular requirements, which lining material to use and the type of electrodes.

The EFM-LDG-W series are suited to water and waste water. The lining is PTFE and the electrodes are stainless steel.

Please note:Electromagnetic flow meters are used to measure the flow of conductive liquid. The measurement side has to be set up correctly at the time of configuring the meter, for best performance, so we need to know the details of the application

  • Features
  • High degree of accuracy
  • Extremely simple operation
  • Self diagnosis for empty pipe Detection
  • Nominal pressure: PN 10, 16, 40
  • Process connection: Flange/clamp etc
  • Lining:PTFE.

The measurement principle of magnetic flowmeters can be described as follows:
when the liquid goes through the pipe at the flow rate of v with a diameter D, within
which a magnetic flux density of B is created by an exciting coil, the following
electromotive E is generated in proportion to flow speed v:
