ULTRASONIC FLOWMETER SENSOR Russian patent published in 1996 - IPC

FIELD: measurement technology; measurement of fluid medium flow. SUBSTANCE: sensor has two ultrasonic transducers mounted on common wall of measuring tube at distance Lm so that their receiving and emitting surfaces form alpha angle with tube wall. Tube walls form rectangular transfer sections HB. Reflector in the form of one or more reflecting planes X and Y forming steps is installed between them on tube wall opposite to radiators. Step height is chosen so as to ensure damping interference of signals reflected from its planes. EFFECT: improved design. 2 cl, 5 dwg
