Wafer Style Electromagnetic Flow Meter

Sandwich type design that saves cost

Water is the most vital utility in any industry, hence Manas has produced an affordable variety of electromagnetic flowmeters for accurate water flow measurement.

Wafer Style electromagnetic Flow Meter, called Jal-Oagh provides the solution to knowing your water use, not only by guesswork but by proper instrumentation with economy and fairly good accuracy.

Sizes available for Wafer Type are DN 50 to DN 200


  • Small in size, light in weight compared to other magnetic meters in its class
  • Full bore electromagnetic flow meter with absolutely no restriction to flow
  • Has a typical accuracy of ± 1 %.
  • Measurement is independent of the velocity profile across the pipe. 
  • Measurement results are independent of density, viscosity, pressure, temperature, solid impurities, and   conductivity variations (above 5 µ S/cm for MFT-01 & above 20 µS/cm for SJ-1101)


  • Effluent Treatment: Untreated as well as Treated Effluent Water Measurement.
  • Sewage Treatment: Wastewater measurement, Sludge measurement etc.
  • Water Supply Schemes: Raw water as well as treated water measurement.
  • In Boiler: Boiler Feed Water Measurement.
  • Chemical Industries: Measurement of acidic & alkaline chemicals & slurries.


  • Fits inbetween the flanges of the pipe which makes it the most compact solution for flow measurement
  • Compatible with all corrosive and noncorrosive liquids
  • Cost-effective and economical flow meter

A wafer style electromagnetic flow meter is a type of flow meter that measures the flow rate of conductive liquids (such as water) by utilizing the principles of electromagnetic induction. It is called “wafer style” because it is designed to be installed between flanges in a pipeline without the need for additional spools or flanges.

Wafer style meters are relatively easy to install and don’t require a lot of space. They are also suitable for a wide range of pipe sizes. Additionally, they provide accurate measurements for conductive liquids with high reliability and low maintenance requirements.
