    1406039 Measuring fluid-flow T L B GRIVERUS 30 Oct 1972 [10 Nov 1971] 49920/72 Heading G1R In a fluid flowmeter having a tangentially arranged inlet 22 and a coaxial outlet 24 in which a ball 30 is driven in a circular orbit, the ball 30 travels along and is held in two grooves 26, 28 while effecting a clearly defined and stable rolling movement. The grooves may have various configurations, Fig. 3-3f (not shown). In further embodiments the ball rotates in grooves formed in rings mounted in the meter chamber, Fig. 6 (not shown), or in grooves formed in mutually facing guide rings arranged in a channel in the meter chamber Fig. 8 (not shown), or in rings 66, 68 having grooves 70, 72, Fig. 10, arranged in a channel 64 in a meter in which the chamber forms a straight flow passage and guide vanes, 74, 76 impart tangential velocity to the flowing fluid. A similar embodiment is described with reference to Fig. 11 (not shown). In yet a further embodiment, Fig. 12 the fluid flows radially with the meter through an inlet 102 or axially through an inlet 102<SP>1</SP> and a tangential velocity is imparted to the fluid by vanes 104. The meter may be completely transparent or provided with windows for use with a photo-electric counting device. A fluid-pressure measuring device, Fig. 13 (not shown) may be used. Magnetic or inductive counting devices may also be used.

    In accordance with the described vortex making, the camera is divided into an introductory zone A, a measuring zone B and an exit zone C having a common center at point 0. The boundary between the first two zones is formed by a cylindrical surface 10 concentrically located in relation to the zones and having a radius corresponding to the distance between iiisHTpOM O and the radial inner side 9 of the tangential entry 5. The boundary between the zones B and C has the shape of a cylindrical surface 11, which forms an imaginary extent of the axial exit 6 vortex oh camera.
    The side wall 4 of the vortex chamber is formed by a spiral in the form of a logarithmic curve, or an Archimedes spiral, or in the form of a combination of these two curves. Such an embodiment of the side wall allows the basic conditions of operation of the entrance zone A of the vortex chamber to be performed, namely, that the flow velocity of the medium in the measurement zone B is uniform everywhere and directed so as to form the same angle with the projection.
    FIG. Figure 3 shows how particles of the current medium that enter the measuring zone B at point 12, chosen arbitrarily, in the direction forming an angle oL with a radius, approach the exit zone C along a spiral groove. The fluid particle passes a series of revolutions around zone B until reaching the exit orifice. The cs # particle size at the entrance to the GO measurement zone consists of the tangential component and the radial component Vj ,. In the next arbitrarily chosen point 13 of radius r along the trajectory of motion, the velocity of the particle with the tangential and radial components and and V.
    These components are components of the movement of the medium through the measuring chamber.
