INTRODUCTIONElectromagnetic water flow meter is ideal for conductive liquids. It is composed of a sensor and an intelligent conversion part. Water flowmeter can measure the volume flow of various conductive liquids. The measured media include acid, alkali, salt and paper pulp, mud, waste water, sea water, and solid-liquid liquids. In addition, the sensor adopts an integral sealed structure, and the measuring tube and the shell are integrated, which is moisture-proof and waterproof, and is suitable for underground or humid environment installation.
