一、前言电磁流量计由于发送器液流部分结构简单,对于液体的适应性较强,适用于各种酸、碱、盐液等导电液体,以及含有固体颗粒(或纤维)的液体。十余年来我国已经生产了几千台电磁流量计,广大用户积累了丰富的使用经验。采用的行业也日益扩展,典型的测量对象如:酒精制药工业的包米浆发酵液(便于杀菌消毒)、石油化工的各种酸碱液、机械制造行业电解切削新工艺的高浓度食盐溶液,采矿采煤工业的矿浆煤浆,石油钻探用水泥灌浆等等。最近还将电磁流量计作适当的改装,试用于含有铁磁性物质的液体流量。 I. Introduction Electromagnetic flowmeter Transmitter part of the flow structure is simple, strong adaptability to liquids, suitable for a variety of acids, alkalis, salts and other conductive liquids, as well as containing solid particles (or fibers) of the liquid. More than 10 years our country has produced thousands of electromagnetic flowmeter, the majority of users has accumulated rich experience in the use. The industries to be used are also expanding. Typical measurement objects include the baguette fermentation broth (for sterilization and disinfection) in the alcohol and pharmaceutical industry, the various acid-base liquids in the petrochemical industry, the high-concentration salt solution for the electrolytic cutting process in the machinery manufacturing industry, Coal mining coal slurry industry, oil drilling cement grouting and so on. Recently, the electromagnetic flowmeter for the appropriate modification, the test for the flow of liquid containing ferromagnetic substances.
