An electromagnetic flowmeter (also known as an “EMF”) is a type of flowmeter that measures the flow of conducting liquids and slurries by utilizing the principles of Faraday’s law of induction. The water flow meter determines the flow rate by utilizing a magnetic field to generate a voltage difference across a conductor moving with the fluid, which is directly proportional to the flow rate.
The electromagnetic flowmeter is a relative-measuring instrument, which means that it measures the velocity of the fluid relative to the instrument, not the absolute velocity. The water flow meter is most commonly used in industrial process control for applications such as determining the mass flow rate of liquids in industrial manufacturing, and it is especially useful in situations where the conductivity of the liquid is high enough.

The factors to consider when choosing a electromagnetic water flow meter
The type of fluid being measured. Electromagnetic flow meters are only suitable for measuring conductive fluids. Non-conductive fluids, such as oil, cannot be measured with an electromagnetic flow meter.
The flow rate range. electromagnetic type flow meters are available in a wide range of flow rate ranges. The flow meter should be selected to match the expected flow rate of the application.
The accuracy requirements. Electromagnetic flow sensorss are very accurate, typically with an accuracy of ±0.1% of full scale. However, the accuracy of the flow meter can be affected by the conductivity of the fluid, the temperature of the fluid, and the presence of bubbles in the fluid.
The temperature and pressure range. Electromagnetic flow meters are typically designed to operate within a certain temperature and pressure range. The flow meter should be selected to match the expected temperature and pressure conditions of the application.
The electromagnetic flowmeter price. Electromagnetic flow meters are typically more expensive than other types of flow meters. However, they are also more accurate and reliable.
The installation requirements. Electromagnetic flow meters are typically installed in-line with the pipe. The installation requirements will vary depending on the specific flow meter model.
The environmental conditions. Electromagnetic flow meters are typically not affected by environmental conditions, such as humidity and dust. However, they can be affected by strong magnetic fields.
