Vorrichtung und Verfahren zur Überwachung der Durchflussrate von Mehrphasenströmungen

Multi-phase fluid flow monitor and method

Dispositif et procédé pour la surveillance du débit d'un fluide multiphasique

Abstract

A monitor (22) obtains signals representative of the gas, oil and water fractions in a multi-phase flow and thereby a density signal representative of the fluid mixture density. A flow meter (26) senses the pressure differential across an orifice plate (30) and provides a fluid flow rate signal in accordance with the pressure differential and the fluid density. Individual gas, water and oil volumetric flow rate signals can thereby be obtained.
