A brief overview of the advantages and disadvantages of electromagnetic flow meters
2011-11-12 10:57:39

The advantages are as follows:

电磁流量计的结构简单,是流量计中运行能耗最低的流量仪表之一。 1) The structure of the electromagnetic flow meter is simple, and it is one of the flow meters with the lowest energy consumption in the flow meter.

使用范围广泛 2) Wide range of uses . 仪表测量管内部无阻碍流动部件,与被测流体接触的只是测量管内衬和电极 ,其材料可根据被测流体的性质来选择。 Because there are no obstructing flow parts inside the measuring tube of the instrument, only the lining and electrodes of the measuring tube are in contact with the measured fluid, and the material can be selected according to the properties of the measured fluid.

3) The electromagnetic flow meter is a volume flow measuring instrument. During the measurement process, it is not affected by the temperature, viscosity, and density of the measured medium and its conductivity (within a certain range). Therefore, the electromagnetic flowmeter can be used to measure the flow of other conductive liquids only after it has been calibrated with water.


着缺点。 Electromagnetic flow meters still have disadvantages.
目前电磁流量计已广泛地被应用于工业过程中各种导电液体的流量测量,如各种酸、碱、盐等腐蚀性介质;各种浆液流量测量,形成了独特的应用领域。 Although the range of use is very wide, the current electromagnetic flowmeter has been widely used in industrial process flow measurement of various conductive liquids, such as various acids, alkalis, salts and other corrosive media; various slurry flow measurement, forming a unique Application areas. 不能用来测量气体、蒸汽以及含有大量气体的液体。 However, there are still some shortcomings. It cannot be used to measure gas, steam, and liquids containing large amounts of gas. It cannot be used to measure liquids with very low conductivity, such as petroleum products or organic solvents. At present, electromagnetic flowmeters are powerless.
