VELOCIMETRE AND METHOD FOR MEASURING THE SPEED OF FLOW OF AN ELECTRICALLY CONDUCTING FLUID

摘要

This velocimetre for measuring the speed of flow of an electrically conducting fluid comprises: - two sensors (16, 19) disposed in such a way that, in the absence of flow of the electrically conducting fluid (4), the difference between the current strengths measured by the two sensors (16, 19) is non zero, - a processing unit (18) is able to calculate the speed of flow of the fluid in a direction parallel to the first measurement direction (7) on the basis of the difference between the current strengths measured by the two sensors (16, 19).
