电磁流量计在分流支管中的应用

The Application of Electromagnetic Flowmeters in Shunt Pipes

为解决目前国内电磁流量计无法同时满足高温、高压、耐腐蚀、大通径流量测量的难题，提出了利用小口径电磁流量计，通过测量分流支管中的流体流量，达到替代大口径电磁流量计测量大流量的目的。文中还提出了延长电磁流量计使用寿命的措施。

To resolve the difficulties of large bore flow measurement of electromagnetic flowmeters meeting all the demands of high temper- ature, high pressure and anti-corrosive features the method of using small electromagnetic flowmeter in shunt pipe as replacement is stated. The measures of prolonging the life time of the flowmeters are also presented.
