本文件的目的是审查磁感应流量计（magmeter）的操作、校准和选择原则。将讨论这些没有活动部件的仪表的性能和可靠性。与目前使用的机械式仪表相比，这种仪表需要的维护更少，而且更精确。磁力计应用范围广泛，包括废水、原水、净化水和创收的测量，以及处理过程的不同阶段，如沉淀水、上清液水和反洗水的测量，以及比例化学添加（起搏）。这些流量计还被广泛应用于大直径城际托管输送管道应用中。

The purpose of this document is to review magnetic inductive flowmeter (magmeter) principles of operation, calibration, and selection. The performance and the reliability of these meters with no moving parts will be discussed. The meters require less maintenance and are more accurate than mechanical meters in use today. Magmeters are used in a wide variety of applications including the measurement of wastewater, raw water, treated water, and revenue generation and in different stages of the treatment process such as the measurement of settled water, supernatant water, and backwash water and for proportional chemical addition (pacing). These meters have also been widely used in large-diameter intercity custody transfer pipeline applications.
