The pulse train is reflected at a target 3 and returned to the other terminal of the analog multiplier 9, where the reflected pulse train is multiplied by the delayed pulse train and delivered to an integrator 11. When the output from the integrator 11 is +1, it means that the corrected delay time is set equal to the reciprocal propagation delay time of a path to be measured, and the distance to the surface 3 of the stored material can be measured by multiplying the delay time by the speed.
