孔板流量计和电磁流量计介质的选择有什么不同？西安华恒仪表为您介绍：
What is the difference between orifice flowmeter and electromagnetic flowmeter?Xi'an Huaheng Instrument for you to introduce:
孔板流量计可以用来测量蒸汽，气体（空气/氮气/二氧化碳气体等）和液体（多为水，自来水，不能有杂志）的瞬时流量和累计流量，是差压式流量计，需要配套差压变送器和流量积算仪才能使用，多适用于高温高压介质，特别是蒸汽的测量。
Orifice plate flowmeter can be used to measure instantaneous and cumulative flow of steam,gas(air/nitrogen/carbon dioxide gas,etc.)and liquid(mostly water,tap water,no magazine).It is a differential pressure flowmeter.It needs a differential pressure transmitter and flow accumulator to use.It is mostly suitable for the measurement of high temperature and pressure media,especially steam.
电磁流量计是用来测量导电液体的体积流量，除可测量一般导电流体如水，河水，空调水，污水等水的流量外，还可用于测量强酸、强碱等腐蚀性液体和泥浆、矿浆、纸浆等液固两相悬浮液体的流量，需要根据不同的介质选择对用的内衬和电极。
Electromagnetic flowmeter is used to measure the volume flow of conductive liquid.In addition to measuring the flow of general conductive fluid such as water,River water,air conditioning water and sewage,it can also be used to measure the flow of corrosive liquids such as strong acid,strong alkali,slurry,pulp and other liquid-solid two-phase suspension liquids.
孔板流量计和电磁流量计都可以测量的介质是水。但是测水的时候选择电磁为优先，性价比高，直接显示，不需要其他附件和配置，性能稳定。
The medium that orifice plate flowmeter and electromagnetic flowmeter can measure is water.But when measuring water,electromagnetism is preferred,the cost-effective ratio is high,the direct display does not need other accessories and configurations,and the performance is stable.
