PURPOSE:To obtain a steam flow meter that allows easy mounting to a main pipe part by forming an annular groove or a room on a mounting flange for a main pipe of a measuring turbine, and providing an annular groove or a room and the center of the mounting flange with subflow tubes. CONSTITUTION:A mounting seat 3b for the measuring turbine part of a main pipe part 1 provided with a short pipe 3 in which an orifice 4 is inserted is joined to the mounting flange 7b of a measuring turbine part 2 having a measuring turbine inside and consisting of a chassis 7, a cover part 8, etc. by a bolt. The flange 7 is provided with an annular groove or a room 7b surrounding subflow routes 3c and 3d of the main pipe part 1, and so composed that the subflow route 3c and a subflow route 7c may be connected by the annular groove or the room 7b, and a subflow route 3a and a subflow route 7d be connected at the center of moutning flanges 3d and 7b respectively. Therefore, even when the measuring turbine part 2 is rotated by 90 deg. against the main pipe part, as the subflow route 3c and the subflow route 7c are connected by the annular groove or the room 7e, mounting becomes easy. |
