Flowmeter magnetic inductive for measuring non-Newtonian liquids.

摘要

FOR MEASURING THE SPEED VM MEDIA AND INDEX OF flow of a liquid non-Newtonian, electrically conductive, flowing in a tube (11) MEASUREMENT, WHICH PART IN CONTACT WITH LIQUID IS nonconductive ELECTRIC, Flowmeter STEP INDUCTION mAGNETIC COVERS IN ADDITION: two coils (12) (13) arranged diametrically opposite relative to each other in the measuring tube, SERVING FOR GENERATING A FIELD (B) MAGNETICO, flowing with a current (I) COIL; Provided TAKE SHAPE ELECTRODE (14), (15) SERVING FOR FIRST AND SECOND INDUCTIVE potential, where a radius (14 {SUB, 1}), (15 {SUB, 1}) BELONGING TO EACH ELECTRODE measuring tube encloses an angle ({} PH) less than 90 GENERATOR-ON COIL CURRENT (21); A switch (22), with which are connectable both coils either in the same direction or in opposite directions in series, and an electronic (24) Valuation consisting of a difference (U {SUB, K}) POTENTIAL DERIVATIVE of the series connection in the same direction and an average speed V {SUB, M} corresponding to the signal (S {SUB, V}) SPEED PROPORTIONAL OR FORM FOR from a difference (U {SUB, G} ) POTENTIAL DERIVED series connection in the opposite direction and the difference (U {SUB, U}) POTENTIAL FORM FLOW iNDEX WITH PROPORTIONAL N SIGNAL (S SUB {N}) flow index. It IS DERIVED still further a difference (D) PRESSURE PIPE FROM measure, also measured CONSISTENCY KY / OR VISCOSITY {EP} {SUB, S} APPARENT FLUID.
