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.

Abstract: A gas-adsorbing device (1) includes: a container (2); a gas adsorbent (3) configured to be disposed inside the container (2) so as to adsorb a gas; and an aeration member (4) having a predetermined aeration rate. The gas adsorbent (3) is disposed in a space formed by the container (2) and the aeration member (4). Further, the space is configured to be completely enclosed by the container (2) and the aeration member (4). In this configuration, it is possible to attain a gas-adsorbing device in which it is possible to reduce consumption of the gas adsorbent due to contact with air, even when the gas-adsorbing device is handled in air.
