Abstract -- This paper describes a novel approach of measuring volumetric flow rate using Electrical Resistance Tomography. Conventional flow measuring techniques are flow-profile dependent and will not produce accurate results unless prior knowledge of the flow profile is known. A brief outline of the various aspects needed to realise an ERT flow meter are presented in this paper. Results produced by the ERT flowmeter were verified with two other independent flow measurement techniques. A brief description of these techniques is given. The results presented in this paper were obtained from experiments involving vertical flow and inclined flow.
Keywords: Multiphase flow, Electrical Resistance Tomography, Flow Profile, Skew Flow.
