1 Scope This Technical Report describes production flow measurement of wet natural gas streams with WGFMs in surface and subsea facilities. Wet natural gas streams are gas -dominated flows with liquids like water and/or hydrocarbon liquids 3) (see 2.67 for a detailed definition). This Technical Report defines terms/symbols, explains the various concepts, and describes best practices of wet gas flow meter design and operation. It addresses metering techniques, testing, installation, commissioning, and operation practices such as maintenance, calibration , and verification. It also provides a theoretical background of this comprehensive, challenging and still evolving measurement technology. There are four general methods in measuring wet natural gas flow. Each approach is detailed below.
— Single-phasegas flow meter with correction factor: Uses a single-phasegas flow meter (often a conventional gas flow metering device) with a correction factor for the effect of liquid on the metering system. In these cases, the liquid flow rate required to determine the correction factor, should be estimated from an external source.
— Two-phaseWGFM: The gas and liquid (both water and hydrocarbon liquid combined) flow rates are predicted with no additional external information regarding the ...
