The measurement principle of the split electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. The split electromagnetic flowmeter is composed of a sensor and a converter. The sensor is installed on the measuring pipeline, and the converter is installed within 30 meters or 100 meters from the sensor. Both They are connected by shielded cables. The main components of the split electromagnetic flowmeter sensor are: measuring tube, electrode, excitation coil, iron core and yoke shell. It is mainly used to measure the volume flow of conductive liquid and slurry in closed pipelines. Such as water, sewage, mud, paper pulp, various acids, alkalis, salt solutions, food slurries, etc., are widely used in petroleum, chemical, metallurgical, textile, food, pharmaceutical, papermaking and other industries, as well as environmental protection, municipal management, water conservancy construction and other fields.
