Eletromagnetic Flowmeters emf 5 G) ~0 }& Z1 `* U7 f! IOf the 20th century, 50-60’s, with the development of electronic technology and the rapid development of a new type of flow meters. According to the electromagnetic flowmeter is Faraday’s law of electromagnetic induction into the conductive liquid is used to measure the volume flow meter. Due to its unique advantages, has been widely used in various industrial processes conductive liquid flow measurement, including a variety of acid, alkali, salt and other corrosive media; various slurry flow measurement, it has developed a unique application areas. In structure, the electromagnetic flowmeter by the electromagnetic flow sensor and converter is composed of two parts. Sensors installed in the industrial process pipeline, Its role is flowing into the pipeline to the liquid flow volume values linear induced to transform into EMFs, and the transmission line through this signal to the converter. Translators from sensors installed in the not-too-distant places, it will be sent by flow sensor signal amplification and and converted signal is proportional to the flow signal output standards, to conduct show that the cumulative adjustment and control
