Infra Red Tomographic Flowmeter

Abstract

This paper is concerned with a new method of measuring a two-phase flow involving solid particles flowing in air. The method made use of an infra red tomographic system. It has the ability to accurately visualize concentration profiles in a pipeline. The imaging is carried out on-line without invading the fluids. The flow meter used a combination of two orthogonal and two rectilinear infra-red projections. Several results are presented in this paper showing the capability of the system to visualize the concentration profile of solids flowing in air.
