摘要

A separating plate (2) is provided inside a housing (1) so as to separate two spaces (11a, 11b) in the height direction. A detection unit (3) is provided in one space (11a) and a sounding body (4) is provided in the other space (11b). Apertures (14) are provided in a side wall (12), thereby opening one space (11a) to the outside environment and letting the fluid to be measured flow into the space (11a). Then, a flow path is formed inside the space (11a) in the housing (1), from the side wall (12) forming the housing (1) toward the detection unit (3), thereby proactively channeling the fluid to the detection unit (3).
