Priority; July 3, 1969 from U.S. Patent Application No. 838,890

The invention relates to flow meters for flowing media, in particular flow meters or flow meters with turbine drive, in which a flow through a knife housing I

^ of the medium set a rotor in rotation, which via gear and associated mechanism connected to a display device which can be appropriately calibrated. With

Turbine-driven measuring devices of this type are known per se and continue to be improved to increase their accuracy.

One of the problems encountered in creating a suitable measuring device of this type relates to the correct positioning of the rotor within the flow path of the medium. If the rotor doesn’t work properly in normal _? ie a right-angled arrangement su the direction of flow of the medium results, as experience shows "Difficulties for precise calibration and obtaining the display on the measuring device." create ,, so that during assembly of the rotor automatically exactly normals, ä _a h "is arranged at right angles to the flow direction of the medium. This is achieved according to the invention . _v that interacting guide devices are provided on the measuring chamber unit and in the measuring device body for the precisely predetermined introduction of the measuring chamber unit into the measuring device housing and that cooperating seating devices are provided on the measuring chamber unit and in the measuring device housing, which engage each other when the measuring chamber unit is in operation in the measuring device housing is appropriate.

According to the invention, there is also a new type of turbine driven To create a measuring device unit »in the case of one

25. The measuring chamber unit 58 has a housing 59 with a outer circumferential wall 61, which is formed at the two opposite ends with smooth cylindrical circumferential surfaces 62 and 63 is ι the smoothly pendulum and are stored exactly on the surfaces 29, 35, 36 and 31 in the device. The top 180 degrees of wall 61 are disposed in opening 25 to form an effective continuation of the main body wall. The case 59 has opposite end faces 64 and 65 "which are smooth, parallel and flat" and are adapted to be closer together sliding contact with the housing sliding surfaces 26 and 27 to fit. At one end the housing wall 61 is grooved at 66, to support a resilient O-ring 67 that sits between the housing 59 and the adjacent housing body surface is compressed to seal against a flowable medium to build. A drain plug 68 is provided as access to the cavity 32 below the housing 59.

• "The housing 59 is provided with an annular inner peripheral wall '71 is provided, which is integral and rigid with the outer wall 61 by means of columns or ribs arranged at the same angular distance 70 and 72 (Figure 8) is attached. This way is a annular flow passage limited by the measuring chamber. On the upstream side of the passage 73 and the wall 71 has

The rotor 75 is of conventional type with an annular rim 76 substantially aligned with the wall JI and a series of helically arranged circumferential blades 77 "Upstream" of the housing 59, a fixed guide body 78 delimiting a flow channel is mounted inside the device housing a. The guide body 78 has a smooth, cylindrical, tubular part 79 on the outside, which ends at and essentially aligned in the longitudinal direction with the edge of the rotor 75 in order to form an annular flow passage part 80 which is aligned with the passage 73 Furthermore, the guide body has a closed, rounded end 81 on the upstream side. The deflector body 78 is held in the housing body with three or more radially arranged fins 82 which are formed in one piece with an annular rim 83 which extends into a shoulder 84 and, for example is attached by means of grub screw 85 "

The deflector 78 is therefore through. Inserting the edge 83 in the shoulder 84 rigidly attached and centric to the flow channel of the device held »The diameter of the deflector

78 is essentially the same as that of the rotor edge 76 and the inner free end of the deflector 78 terminates in the vicinity, but a small distance in front of the rotor rim 76.

The discharge channel sections 73 and 80 are thus in the longitudinal direction with one another and with the circumference occupied by the blades of the rotor 75 aligned so that everything is in the meter housing The flowing medium, properly directed through the rotor blades, will do a proportional rotation of the rotor.

In common to Figures 1, 2 and 12 to 15, the rotor 75 is attached to a küi'isontalen rotor shaft 87, which is freely rotatable in bearings 88 and 89 attached to an inner type 91. At the end adjacent the rotor, the inner bracket 91 has an enlarged cylindrical flange 92 which fits into the cylindrical inner surface of the wall 71 and a cylindrical end flange 93 which fits into a cylindrical end recess 94 in the wall 7 ". A resilient O-ring seal -5 (FIG. Z) is pressed in between the flanges 92 and 95 and the end of the wall 71.

At its other find is the inner girder 91Htt upper and lower threaded bores 96 (Figure 13) formed in the

The opening 155 surrounds the cylindrical, hub-like rope 16O ₉ to align the measuring chamber circumferentially around the flow axis and in the longitudinal direction to the flow axis, but with small, sufficient play to compensate for manufacturing tolerances.

The plate 152 can also serve as an extractor. When the cover plate 41 is removed from the case body should, normally the entire Hess chamber unit 58 moves with her. But if the housing 122 should strive to pull themselves out of the bore 120 * su, the plate 152 picks up the snap ring 158 and lifts the measuring chamber.

According to FIG. 10, the coupling element 137 carrying the drive magnet is held on the pin 131 by the ring 130. the Bearings 139 and 140 are spaced apart by a spacer 141 *, but they are rotatable about pin 131 and displaceable along this pin 131. This enables the magnet 142 to be in optimal longitudinal association with the magnet 145 raises when the latter surrounds it to during operation to reduce axial shear forces.
