Claims

[Scope of Claim for Utility Model Registration] (1) A support device for movably supporting measurement instruments such as probes and smoke line nozzles for measuring fluid flowing in a fluid tank in a fluid tank, the cross-sectional outline of which is streamlined. The inside is hollow, and at least the inner end of the tank is sealed, and a rotary shaft having a probe at the tip is passed through the hollow inside the tank, or a smoke line nozzle is passed through the sealed end. 1. A fluid measurement instrument support device, characterized in that a movable shaft configured to be attached to an end of the fluid tank in communication with a hollow portion is attached to a stand provided outside a fluid tank so as to be movable in the vertical direction. (2) The intermediate portion of the streamlined movable shaft is supported by a guide block so as to be movable up and down, and is mounted so as to increase support rigidity against fluid resistance or vibrational force received from the fluid. 2. The fluid measuring instrument support device according to item 1.
