Remote Measurement Methods of Fluid Flow Based on Pressure Wave Transmission

Abstract

Abstract:

In order to achieve a remote measurement for fluid flow,research was made on theoretic models and experimental measurement methods for transmission pressure wave of the horizontal pipeline.A transmission line modeling(TLM) network modeling method was used to measure the pressure wave attenuation of the horizontal pipelines in the downstream from the flow meter,the theoretic data was also obtained by using its theoretic models.It is found that the theoretic models and experimental results are matched closely.It has shown the values of such a theoretic model and the feasibility of the remote measurement of fluid flow.
