Abstract: A system for measuring flow rate in a pipeline by use of a surface jet pump that receives input from both a high pressure pipeline and a low pressure pipeline. Rather than installing flow meters at any or all of the inputs/output from the SJP which is an expensive undertaking, flow rate is predicted by utilising existing pressure sensors located on the high pressure pipeline, low pressure pipeline and discharge pipeline respectively. A control processor predicts flow rate based on correlations between flow rate and pressure for a given SJP geometry and, for example, utilises momentum, conservation of mass and continuity equations, balanced against the pressure forces and velocity in the SJP.
Abstract translation: 一种用于通过使用接收来自高压管道和低压管道的输入的表面喷射泵来测量管道中的流量的系统。 不是在SJP的任何或所有输入/输出中安装流量计，这是昂贵的工作，而是通过利用位于高压管道，低压管道和排放管线上的现有压力传感器来预测流量。 控制处理器基于给定SJP几何形状的流速和压力之间的相关性来预测流量，并且例如利用与SJP中的压力和速度平衡的动量，质量守恒和连续性方程。

Abstract: The apparatus consists of modular stages arranged in series, each stage including a main chamber and a nozzle opening. In practice, a fluid passing through the opening is subject to a pressure drop as it enters a main chamber of a subsequent stage in the series. This multi-stage pressure drop avoids a sharp drop in temperature, as would occur if the total pressure drop was achieved in one stage, that may cause hydrates to form in an oil/gas pipeline.
