5 Key Reasons to Consider Electromagnetic Flow Meter for Wastewater Treatment

February 28, 2022

According to the report summary, electromagnetic flow meter occupies around 60% of the market share and is projected to grow at a CAGR of 5.5% in the forecast period of 2022-2027. Considering so many varieties of flow meters on the market, magnetic flow meter can be considered as the most common especially in wastewater industry. Why is it?

Reason 1

Electromagnetic flow meters have high accuracy(0.50%) and higher accuracy can be customized.

Reason 2

Electromagnetic flow meters can be used on different pipe diameters from small DN(10mm) to quite large DN(2000mm).

Reason 3

Electromagnetic flow meter does not have any moving parts. Where debris might hinder and damage other kinds of flow meters, magnetic meters actually require some sediment and particulates, making them ideal for wastewater solutions or water-based filthy liquids, or other applications where low-pressure drop and low maintenance are required.

Reason 4

Electromagnetic flow meter generally consists of 5 parts (flange, liner, electrodes, sensor and transmitter). A wide range of liner and electrode options accommodate various process applications.

Reason 5

Affordable price. Compared with other flow meters, magnetic flow meter is cost effective so it's preferably considered by wastewater plants in terms of all the above-mentioned aspects.


One thing to note is that electromagnetic flow meters will generally not work with hydrocarbons, distilled water, and many non-aqueous solutions or liquids whose electrical conductivity is less than approximately 5μS/cm. So do not consider magnetic flow meters if your application is regarding it.
