Orifice Meter Diagnostic Systems Use of Differential Pressure Diagnostics to Identify Various Issues Class # 4260.1

摘要

Orifice plate meters are popular for being relatively simple,reliable and inexpensive.Their principles of operation are relatively easy to understand.Although seen as a traditional mature metering technology,as with all flow metering technologies,the orifice meter is continually being developed.Significant developments in the last decade include significant improvements of DP transmitter capabilities,wet gas flow algorithm published by ISO,and a comprehensive validation system.This orifice meter validation system operates through a comprehensive diagnostic tool.This paper discusses this orifice meter validation system('Prognosis') developed by DP Diagnostics and now available on multiple platforms by different suppliers.
