Claims

[Scope of Claim for Utility Model Registration] 1. A detection tube is arranged protruding from the front part of the detector body, and a total pressure hole and a static pressure hole are provided at the tip of the detection tube arranged in the fluid piping, The detector body and the detection tube include a total pressure passage that communicates the total pressure hole and a flow rate indicator connected to the rear end of the detector body, and a static pressure passage that communicates the static pressure hole and the flow rate indicator. In the flow rate detector, the detection tube is fixed to the detector body, and two on-off valves for opening and closing the total pressure passage and the static pressure passage, respectively, are installed in the detector body. A flow rate detector characterized in that it is arranged so that it can be operated from the outside. 2. The flow rate according to claim 1, wherein one of the total pressure passage and the static pressure passage is opened at the center of the rear end surface of the detector body, and the annular groove of the other passage is recessed in the outer periphery of the opening. Detector.
