RÉSUMÉ

This paper presents the experimental setup and the first measurement results of a novel device for the contactless flow rate measurement in poorly conducting fluids. The device relies on the technique of Lorentz force velocimetry (LFV) which has been intensively studied by Thess et al. [1]. The results of our investigation show for the first time the feasibility of LFV in fluids with conductivity less than 10 Sm−1. Here, the forces to be measured are in the order of magnitude of 10−5 N.
