Flow-Rate Measurements of Solid Particulates and Liquids Using Doppler Effect

Abstract

A technique for monitoring the flow rate of granular materials and liquids using Doppler effect is dealt with both theoretically and experimentally. Two methods are used and comparison between them is drawn. The method used is more practical than conventional methods (e.g. obstruction meters and turbine meters) in the sense that it does not obstruct the flow of material, change the flow pattern and assist the formation of blockages.

The technique is applicable in wide variety of conveying systems where the material is conveyed on a belt or falls freely under gravity.
