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.

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.

A pressure switch is a device that monitors the pressure in the system and automatically responds to changes in pressure, turning on or off devices depending on the set pressure thresholds. Pressure switches are widely used in hydraulic and pneumatic systems and other applications requiring pressure control.
