<p>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.</p> |
