一、进口智能型电磁流量计概述

进口智能型电磁流量计由传感器和转换器两部分构成。它是基于法拉第电磁感应定律工作的，用来测量电导率大于5μS/cm导电液体的体积流量，是一种测量导电介质体积流量的感应式仪表。除可测量一般导电液体的体积流量外，还可用于测量强酸强碱等强腐蚀液体和泥浆、矿浆、纸浆等均匀的液固两相悬浮液体的体积流量。美国威盾VTON进口智能型电磁流量计广泛应用于石油、化工、冶金、轻纺、造纸、环保、食品等工业部门及市政管理，水利建设、河流疏浚等领域的流量计量。

The intelligent electromagnetic flowmeter consists of two parts: a sensor and a converter. It is based on Faraday's law of electromagnetic induction and is used to measure the volume flow rate of conductive liquids with a conductivity greater than 5 μ S/cm. It is an induction type instrument for measuring the volume flow rate of conductive media. In addition to measuring the volume flow rate of general conductive liquids, it can also be used to measure the volume flow rate of strong corrosive liquids such as strong acids and alkalis, as well as homogeneous liquid-solid two-phase suspensions such as mud, slurry, and pulp. Intelligent electromagnetic flow meters are widely used in industrial sectors such as petroleum, chemical industry, metallurgy, light textile, papermaking, environmental protection, food, municipal management, water conservancy construction, river dredging, and other fields for flow measurement.
