ULTRASONIC METHOD OF MEASURING SPEED OF FLUX AND DEVICE FOR REALIZATION Russian patent published in 1995 - IPC

FIELD: measurement technology. SUBSTANCE: device has discharge converter, two piezoelectric converters, probing pulse former, amplifier-former, OR circuit, change-over delay two univibrators, direction trigger, mode trigger, comparison inhibition univibrator, time selector, univibrator, generator starting trigger, pulse convergence trigger, integrator starting trigger, pulse convergence trigger, integrator, generator, counter-divider, three decoders, transient mode trigger. Time of passing non-measuring sections of sync rings by pulse is predetermined and value of convergence of sync pulses of two sync rings is found according to mathematical equation. EFFECT: elimination of error due to signal delay in electronic circuits. 2 cl, 2 dwg
