ULTRASONIC PHASE-PULSE FLOW RATE METER

摘要

An ultrasonic phase-pulse flow rate meter includes two emitting inclined piezoelectric transducers connected to respective outputs of generator of sounding impulses, two receiving inclined piezoelectric transducers connected to respective blocks for processing measuring information, blocks for control of operation of generator of sounding pulses, and measuring block. The block for processing measuring information is additionally equipped with a unit for determination of angle of phase shift between signals of receiving piezoelectric transducers by parameters of interferential ellipse and electronic device for correction of measuring information on non-identity of acoustic channels.
