Abstract
The present disclosure provides an ultrasonic transceiver capable of stably measuring a fluid of high temperature and high humidity for a long period, and provides an ultrasonic flowmeter, an ultrasonic flow velocimeter, and an ultrasonic densitometer each including the ultrasonic transceiver. An ultrasonic transceiver (1) comprises a piezoelectric body (3) and an acoustic matching body (2) disposed in one face of the piezoelectric body (3), wherein the acoustic matching body (2) includes: a top plate, a bottom plate, and a side wall that define a closed space; and a perpendicular partition wall formed substantially perpendicular to the bottom plate and adhering to the top plate and the bottom plate, thereby dividing a closed space.
