Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

The Venturi meter is commonly used in combination with other sensors for the measurement of gas fraction and water cut as part of a multiphase flow meter system for the measurement of oil, water and gas flowrates. The Venturi differential pressure signals are generally interpreted using empirical corrections to a momentum equation to give a solution for volumetric flowrate. In this project the use of advanced processing techniques and neural networks have been used to examine the potential improvement in measurement performance which may be obtained from a system incorporating a standard Venturi tube in combination with a gamma densitometer. The data is pre-processed before being applied to a neural network using simple statistical methods combined with some signal processing techniques. It has been found that this neural network solution performs extremely well when only predicting the gas and liquid phases. Poorer performance was registered when trying to predict all three phases, indicating the need for a water cut sensor.
