Abstract
The method and arrangement contemplates transmitting externally triggered trigger pulses by means of a magnetostrictive line or conductor and such produces echo pulses. Displacement path and time oscillator pulses are counted by two counter groups, and there is computed from the counter state the velocity-corrected position of a measuring head. Consequently, with a higher measuring rate there can be appreciably increased the accuracy of the evaluation of the pulses delivered by the ultrasonic measuring system, there can be obtained further measuring data (velocity and acceleration) by means of the moving measuring head, and there is possible an absolute measurement. Additionally, the resolution of the measured displacement path or distance can be randomly selected by means of the frequency of the displacement path or distance oscillator.
