Contactless electromagnetic induction flowmeter based on phase shift measurements

Priede, J.; Buchenau, D.; Gerbeth, G.

This study is concerned with a conceptual design of a new contactless AC induction flowmeter for liquid metal flows. The basic idea is to make use of the fact that the fluid flow disturbs not only the amplitude but also the phase distribution of an applied AC magnetic field. The goal is to consider the possibility of using the fluid flow induced phase shift of an AC magnetic field to measure the flow rate. In order to figure out the basic characteristics of such a flowmeter we consider several simple theoretical models where the liquid flow is approximated by a solid body motion. Based on these ideas a laboratory model of such a flowmeter has been built and tested at a liquid metal flow.
