A multiphase flowmeter, and a method of analyzing and measuring multiphase flow through an inline conduit is described. The multiphase flowmeter includes a combination of three flow elements 1, 2 and three differential pressure sensors 3, 4, 11. The pressure differentials can be caused by a variety of means such as a flow obstruction within the flow element. The meter also has a pressure transmitter 6 which measures the in-pipe pressure and a temperature sensor 7 which measures the fluids temperature. From the signals obtained from the above sensors, an overall analysis of the multiphase fluid flow is performed providing a complete set of flow measurement data for a fluid mixture composed of three phases, which three phases may be oil, water and gas, or in the case of a wet gas application, gas, gas condensate and water. Preferably the differential pressure sensors are miniaturized to be internalized within the in-line conduit and integrated within the differential pressure flow element. |
