电导率仪测定tds

本文章主要介绍了：电导率仪测定tds,电导率仪使用 维护和保养规程,电导率仪怎么组装,电导率仪测定tds等信息

1）电磁流量计的传感器结构简单，测量管内没有可动部件，也没有任何阻碍流体流动的节流部件。所以当流体通过流量计时不会引起任何附加的压力损失，是流量计中运行能耗***的流量仪表之一。
2）可测量赃污介质、腐蚀性介质及悬浊性液固两相流的流量。这是由于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。例如，用聚三氟乙烯或聚四氟乙烯做内衬，可测量各种酸、碱、盐等腐蚀性介质；采用耐磨橡胶做内衬，就特别适合于测量带有固体颗粒的、磨损较大的矿浆、水泥浆等液固两相流以及各种带纤维液体和纸浆等悬浊液体。
