A. Trachtler et al., TOMOGRAPHIC METHODS IN ELECTROMAGNETIC FLOW MEASUREMENT FOR DETERMINING FLOW PROFILES AND PARAMETERS, TM. Technisches Messen, 64(10), 1997, pp. 365-373
The functionality of conventional electromagnetic induction flowmeters
can be extended using multiple electrode and/or coil pairs. After mod
elling the signal generation with special regard on the spatial distri
bution of the fluid flow velocity, three extended flowmeters are prese
nted: a multiple-electrode flowmeter with minimized flow profile depen
dency, a model-based method for viscosity measurement of non-Newtonian
fluids, and a multiple-electrode/multiple-coil system for non-paramet
ric flow profile reconstruction.
