Abstract

A system for metering flow of a fluid has a vibratable flowtube for receiving a multiphase fluid flow. A driver is configured to vibrate the flowtube. A pair of sensors is positioned to detect movement of the flowtube at different locations on the flowtube. Pressure and temperature sensors are positioned to measure a pressure of the fluid. One or more processors are configured to use a phase difference between the sensor signals to determine a fluid flow rate through the flowtube. The one or more processors are further configured to determine an amount of dissolved gas in the multiphase fluid using the pressure, the temperature, and the relative amounts the multiple liquids in the multiphase fluid.

本发明涉及一种用于负责说明溶解气体的多相流计量的系统和方法。一种用于计量流体流动的系统,包括用于接收多相流体的可振动的流管.驱动器配置成用于使流管振动.一对传感器定位成用于检测流管上不同位置处的流管的运动.压力传感器和温度传感器定位成用于测量流体的压力.一个或多个处理器配置以利用传感器信号间的相位差来确定通过流管的流体流率.所述一个或多个处理器进一步配置以利用多相流体中的压力、温度和多种液体的相对量来确定多相流体中的溶解气体量。
