Technical Modification on Metering System of Natural Gas

CWD-430 orifice flowmeter is used in Zhenwu Natural Gas Processing Plant to measure the flowing volume of natural gas.This kind of orifice flowmeter has problems of low metering precision and complicated structure.A technical reform is made to improve the metering accuracy through installing SWP flow totalizer and packaged orifice valve of high grade,which realizing parameter acquisition of flow rate and pressure of natural gas in automatic way.Modification results show that metering accuracy of natural gas meets the needs of gas processing production and outer transmission,thus automatic management level is raised as well.
