Abstract:
Established wet gas metering techniques are typically based on differential
pressure devices, and their measurement accuracy is still unsatisfactory to
natural gas industry. Coriolis mass flowmeter (CMF) is the most superior flow
measurement technology at now, it can provide mass flowrate and density output
simultaneously. Putting CMF into wet gas metering may be a reasonable and high
accuracy solution to natural gas industry demands. The problems and advantages
of CMF in gas-liquid two-phase flow metering has been analyzed, a serious
experiments has been carried out to test the possibility and feasibility of CMF
as wet gas meter. Experimental conclusions are promising,CMF can work properly
in wet gas metering condition, and the repeatability test of CMF is perfect, and
the relationship between the true mass flowrate and CMF readings are almost
linear. When gas flowrate is kept to a constant, CMF can follow the variations
of liquid flowrate accurately. At last, some open problems deserving further
investigation are propose
