heal.abstract	A new sensor for measuring liquid's flow rate in closed conduits is presented. This sensor utilizes two amorphous negative magnetostrictive wires. One of them is prestressed and firmly fixed at the walls of the conduit, being under additional stress when the liquid flows. This stress is detected by means of a magneto-inductive pulsed voltage output at the end of the wire. The second wire is fixed at the one end inside the conduit, in order to be orthogonal to it, so that flowing liquid causes displacement and bending on it. Such displacement is detected by means of a linear variable differential transformer, its primary and secondary windings being along the length of the fluid conduit. Experimental results indicated that different rates of flowing fluid can be detected by the two techniques. © 1997 Elsevier Science S.A.	en
