Abstract: The internal pipe wall of the Electromagnetic Flowmeter (EMFM) must be non-conductive to prevent the generated electromotive force from short-circuiting. Usually the inside of metallic pipes is lined with insulating material. The lining limits the applicable temperature range of measured fluid and also its reliability. A new structure is proposed, in which the insulating liner is eliminated and replaced with non-insulation material. A potential distribution is formed on the pipe wall by applying voltage proportional to fluid flow rate. The potential distribution is decided by the conducting pipe wall. In this paper theoretical analysis and experimental results of EMFM with non-insulation pipe wall are described.
