SENSOR ASSEMBLY FOR FLOW METERS

Abstract

The invention relates to a sensor assembly (1) comprising a housing (3a, 3b) consisting of a tubular part (3b), a membrane (4), a cable (5), an ultrasonic sensor (6), and another sensor (2); in which the tubular part (3b) includes the first end; in which the tubular part (3b) is connected to the membrane (4) at the first end of the tubular part (3b); in which the ultrasonic sensor (6) includes a piezoelectric transducer and a coiled electrode; in which the piezoelectric transducer includes the first and second sides, the second side of the piezoelectric transducer being arranged opposite the first side of the piezoelectric transducer; in which the first side of the piezoelectric transducer is attached to the membrane (4); in which the coiled electrode includes the first and second sides, the second side of the coiled electrode being arranged opposite the first side of the coiled electrode.
