毕托巴流量计在蒸汽测量中的应用

扫码查看
在蒸汽流量测量技改项目中,选用毕托巴流量计替代原超声波流量计.在技术协议谈判过程中,要求取消冷凝罐,并采用直接在管道正上方安装的方法进行测量.对根部阀进行改进,将原有的针形阀更换为直通闸阀,并在设计上取消了仪表伴热.使用结果表明,变送器未受高温影响,其温度和环境温度一致;该流量计测量灵敏、稳定,改造效果显著.
Application of the Bithoba Flowmeter in Steam Measurement
In the steam flow measurement technology renovation project,the Bitoba flowmeter was selected to replace the original ultrasonic flowmeter.During the negotiation of the technical agreement,it was requested that the con-densate tank be eliminated and that the measurement be carried out by installing it directly above the pipe.Improvements were made to the root valve by replacing the original needle valve with a straight through gate valve and eliminating instrument heating in the design.The usage results indicate that the transmitter is not affected by high temperature and its temperature is consistent with the ambient temperature.The flowmeter is sensitive and stable in measurement,and the improvement effect is significant.
