图1电磁流量计变送器部分的原理示意图电磁流量计的特点是能够测量酸、碱、盐溶液以及含有固体颗粒(例如泥浆)或纤维的液体。电磁流量计通常由变送器和转换器两部分组成。被测介质的流量经变送器变换成感应电势后,再经转换器把电势信号转换成标准的(4～20)mA直流信号输出,以便
Figure 1 Electromagnetic flowmeter transmitter schematic schematic Electromagnetic flowmeter is characterized by the ability to measure acid, alkali, salt solution and the liquid containing solid particles (such as mud) or fiber. Electromagnetic flowmeter is usually composed of two parts transmitter and converter. The flow of the measured medium is transformed into the induction potential by the transmitter, and then the potential signal is converted into the standard (4-20) mA DC signal output by the converter so that
