Abstract:
An ultrasonic flow meter unit, mounted to a fluid passage through which a measurement target fluid flows, comprises a pair of ultrasonic transducers each including a piezoelectric substrate, and an acoustic matching member; a measuring circuit which measures a flow of a target fluid based on time for which an ultrasonic pulse propagates between the pair of ultrasonic transducers; and an insulating damping member unitarily formed to cover at least a portion of each of a portion of each of the pair of ultrasonic transducers, which portion contacts the fluid passage, the piezoelectric substrate, and the measuring circuit.
