Abstract

The invention relates to the measurement of the discharge of a running fluid based on two ultrasound signals transmitted simultaneouls in opposite directions between two ultrasound sensors. By the method n chronometric signals CKi are formed, i having the values from 1 to n, which signals are mutually phase-shifted by 2 /n, the first chronometric signal labelled as CLS which appears immediately after the apperance of the characteristic section of the first ultrasound signal SIG1 received is identitied and stored. The time t1 is determined which time corresponds to the sum of time intervals of an integer m successive periods between the moment in which the characteristic section appears of every of the m periods of signal SIG1, and the time in which the subsequent signal CLS appears. In a similar manner time t2 is determined for signal SIG2, produced in opposite direction which corresponds to the sum of time intervals of m successive periods between the moment in which the characteristic section of each period and the moment when subsequent CLS signal appears. The difference (t2-t1) is recorded and the discharge is subtracted. 26 claims, 17 figures
