摘要： A turbine meter comprising a casing of substantially hollow cylindrical shape installed within a conduit through which a fluid to be measured is flowing, an axle member supported within the casing and having an annular recess therearound; a longitudinal flow passage formed in the axle member, a plurality of discharge holes formed in the axle member to connect communicatively the annular recess and the flow passage, a supply pipe inserted into said conduit through the wall thereof and functioning to supply a pressurized fluid to said flow passage in the axle member, a vane wheel comprising a hub disposed around said annular recess with minute gaps therebetween and adapted to rotate in a substantially non-contacting state relative to the axle member and a plurality of vanes implantedly fixed at their root parts to the hub, said vane wheel being rotated by a portion of the fluid being measured which flows through the casing, and means for detecting the rotation of the vane wheel. The pressure of the pressurized fluid and the dimensions of said minute gaps are selected at values to cause forces acting on the vane wheel during rotation thereof and urging the vane wheel to undergo displacement in the thrust direction to be mutually cancelled, whereby the vane wheel rotates in a state of stable equilibrium.
