Header How to Effect Orifice meter in Natural Gas Flow Measurement
Lai Zhongze, Li Xiaobo
Abstract:
The header is typical disturb of natural gas transport station. Natural gas flow measurement is mostly by orifice meter in the nation. Mostly orifice standard doesn’t act the header as "typical disturb", they only act it as "other disturb", so it needed pipeline length is longer than the standard prescriptive pipeline length. This paper introduces the orifice meter in different place which is installed after header in natural gas flow measurement and analyses, so can get the first conclusion, so can help the man who measure by orifice meter in the gas station.
