A water flow meter is a key device used in various sectors of industry and municipal economy. Water flow meters allow for optimization of water consumption, process quality control and settlement with suppliers. Selection of the appropriate water flow meter depends on many factors, including required measurement accuracy or operating conditions. A different water flow meter should be used for gravity flow (partial pipe), water in pressure systems or for open channels.

We have already delivered nearly 1,000 electromagnetic flowmeters to our customers. The experience we have gained has shown us the most common problems encountered by designers, installers, and users of these devices. In this article, we will focus on the proper selection of an electromagnetic flowmeter.

An electromagnetic flowmeter is a device used to measure the flow of electrically conducting liquids. Electromagnetic flowmeters are widely used in the water supply and sewage industry to measure water and wastewater flow. They are also used in measuring the flow of technological water (e.g. in mines) or in the food industry (e.g. juice production, dairies). The device works on the principle of Faraday's law of electromagnetic induction and uses the phenomenon of electromagnetic induction.
