Abstract

844,026. Flow meters. EKSTROM, R. A. Jan. 26, 1959, No. 2804/59. Class 69 (1). In a flow meter comprising a casing 15 forming a flat chamber having an inlet 21 and an outlet 23 at opposite sides of a vane 28 swingably mounted in the chamber, indicating means 33 being provided to show the momentary position of the vane in the chamber, the vane 28 comprises a flexible blade having a portion 30 curved through an angle in excess of 180 degrees, the end portion of the blade member to one side of the curved portion 30 being secured to the casing by means such as a bolt 29, while the other end of the blade member extends towards a wall 27 of the chamber that is curved so as to provide a gradually increasing space between the free edge of the blade member and the wall as the blade moves in the direction from the inlet 21 to the outlet 23. The curved wall 27 comprises the surface of a detachable element 25 insertable in the chamber. An armature 31 of soft iron or magnetic metal is mounted on the vane 28 or it may be integral with the vane. A pointer 33 is mounted on a pivot 34 in bearings 35 on a cover 18 (Fig. 2). A magnet 36 is attached to the pointer. A counter balance 37 is provided on the pointer. In operation, fluid entering the inlet 21 impinges in the vane 28. As the blade moves the curved portion 30 will be " wound up " so that the blade moves around movable centres x, y, z (Fig. 4). This causes the outer end of the blade to travel on a curvilinear arc which permits the calibration to be spaced almost evenly. As the vane moves the magnet 36 which is magnetically coupled to the blade 28 through the armature 31 causes the pointer 31 to move across a scale 38 on the cover. In a modification shown in Figs. 6 and 8 the vane 47 is provided with an elongated magnet 50 formed with longitudinal slots 51, 52 which are engaged by pivot points 53, 54 on the cover 53 and body 54 respectively. A pointer 55 is provided with an armature 56 to coact with the magnet 50. In a further modification shown in Fig. 10 the measuring scale 72 is calibrated directly on the upper face of the case.
