Claims

[Scope of utility model registration request]

(1) A cylindrical body with a bottom formed so that a portion extending from one end to an appropriate length can be inserted into the pipe through an insertion port consisting of a branch pipe provided in the pipe and a gate valve connected to the branch pipe. and a flow velocity detection section that is pivotally supported at one end of the main body and rotated by a drive mechanism provided in the main body, and the flow velocity detection section and the main body are arranged so that their respective axes are parallel to each other. The main body is fixed to the insertion port by inserting the pipe into the pipe while the fluid is flowing through the insertion port, and the flow velocity detector is rotated by a desired angle via the drive mechanism to remove the pipe. A flow rate measuring device characterized by measuring the flow rate of an internal fluid at a desired point.

(2) Flow velocity measurement according to claim 1, wherein the flow velocity detection section is formed as an ultrasonic flow velocity sensor having ultrasonic transducers attached to both ends of an arm. Device. (31. Utility model registration claim characterized in that the flow rate detection section is formed in a Pitot tube having an arm shape with one end pivotally supported and having at least one total pressure measurement hole in the longitudinal direction. 1. The flow rate measuring device according to item 1.
