ABSTRACT:
A multiphase flowmeter, and a method of analyzing and measuring multiphase flow is described. The body of the multiphase flowmeter consists of the following components. It has a straight flow pipe in which two orifice plates a lodged near the extremities. At each of these two locations, a pressure differential transmitter measures the pressure drop that occurs as the fluid passes through the orifice plates. Along the length between the orifice plates, an ultrasound Doppler sensor measures the volume flow rate of the multiphase fluid, a pressure transmitter measures the in-pipe pressure and a temperature sensor measures the 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 the mixture and for each of the three phases consisting of oil, water and gas.
