Abstract

In this paper we present a fluid flow-meter based on the inductive response of glass covered FeSiB amorphous wires, arranged as vertical active cores with respect to the flow of a liquid in a pipe of circular or rectangular diameter. Arrays of parallel FeSiB glass covered wires, fixed at the one end and free at the other are set normal to the fluid flow inside of an array of thin coils, thus covering the whole cross section of the fluid conduit. An excitation coil is also used for static flow measurements. The displacement of each glass covered wire corresponds to the local velocity of the fluid. It has been determined that the uncertainty of the voltage output dependence on the fluid flow is better than 1%. So, the profile of the fluid velocity along the cross section of the fluid conduit can be determined.
