Using a sonic delay line approach, the distance of a point from the ends of a wire is measured by the time required for an acoustic pulse to move along a wire. A magnetostrictive wire extends between its endpoints with several magnetic pickup coils connected in series located at each end of the wire
In an acoustic pulse delay line system for measuring the distance along a magnetostrictive wire from a first point on said wire to a second point on said wire including means for measuring the time required for a pulse to move between said points with a magnetoacoustic pulse generator at said first
