科恩科KNKE电磁流量计是一种常用的流量测量仪器，用于测量液体或气体在管道中的流量。它通过感应电磁场来测量流体的流量，利用法拉第电磁感应定律，在导电介质（如水、污水等）中通过两个电极产生磁场，当导电介质在磁场中流动时，会在两个电极间产生感应电动势，这个感应电动势与介质的流速成正比，从而实现了流量的测量。

电磁流量计的工作原理是利用液体或气体中带电颗粒的运动状态改变磁场的感应电动势，通过检测感应电动势的大小来计算流速和流量。

电磁流量计的测量范围较宽，精度高，可用于各种液体和气体的测量，特别是对于带有固体颗粒和腐蚀性介质的测量，电磁流量计也具有很好的适用性。

电磁流量计广泛应用于水处理、化工、食品、医药、石油化工等领域，是目前流量测量领域中最常用的一种流量计。

An electromagnetic flowmeter is a commonly used flow measurement instrument that is used to measure the flow of liquids or gases in pipes. It measures the flow of fluid by sensing the electromagnetic field produced by the flow of the fluid. It works on the principle of Faraday's law of electromagnetic induction. In a conductive medium, such as water or wastewater, a magnetic field is generated by two electrodes. When the conductive medium flows in the magnetic field, an induced electromotive force (EMF) is generated between the two electrodes. This induced EMF is proportional to the flow rate of the conductive medium, and this makes it possible to measure the flow rate accurately.

The operating principle of an electromagnetic flowmeter is to detect changes in the induced EMF caused by the movement of charged particles in the liquid or gas being measured, and to use the detected changes in EMF to calculate the flow velocity and flow rate. The electromagnetic flowmeter has a wide measuring range, high accuracy, and can be used to measure a variety of liquids and gases. It is particularly suitable for measuring media containing solid particles and corrosive media.

Electromagnetic flowmeters are widely used in water treatment, chemical, food, pharmaceutical, petrochemical, and other industries. They are currently the most commonly used flowmeter in the field of flow measurement.
