LORENTZ FORCE VELOCIMETRY USING ELECTROMAGNETIC FORCE COMPENSATED LOAD CELLS

C. Diethold, S. Vasilijan, T. Fröhlich

Abstract:

This paper discusses the flow rate measurement of poorly conducting fluids (such as electrolytes) using Lorentz force velocimetry (short: LFV). The Lorentz force caused by the moving electrolytes is in the range of micronewton. This tiny Lorentz force is determined using a high resolution force measurement systems based on electromagnetic force compensated (short: EMC) load cells.
In this paper the force measurement system, the principle of LFV and the environmental influences on this kind of force measurement system are described.
