APPARATUS AND METHOD FOR MEASURING FLOW OF GAS WITH ENTRAINED LIQUIDS
摘要
An apparatus and method for making and using two measurements to correct metered flow rate values when liquids are present in a multiphase flow stream. The apparatus includes a conduit (10), an orifice (12) positioned within the conduit for creating differential pressure, a gamma ray densitometer including a radient energy source (22) and a radient energy detector (26) placed at an upstream side of the orifice for measuring upstream cross-sectional area and a pressure recovery port (34) placed downstream of the orifice for measuring the pressure recovery value.
