Abstract
911,612. Measuring fluid flow electrically. GENERAL ELECTRIC CO. Ltd. Sept. 6, 1960 [Sept. 8, 1959], No. 30620/59. Class 40 (1). [Also in Group XXIX] Apparatus for measuring fluid flow comprises a disc with a series of peripheral vanes, subjected to a torque by fluid flow, and electromagnetic means for producing an equal and opposite torque in the disc, the current through the electromagnetic means being proportional to the rate of fluid flow. As shown (Figs. 2, 3), the disc 6 has its periphery shaped into a series of vanes, and is mounted on a pivot 5 for rotation about its axis as limited by holes 12 in the disc through which pass screws 10 fixing a bearing plate 7 to a conical supporting member 2. Downstream of the disc, a U-shaped core 13 fixed to the cylindrical housing 1 is energized by a coil 18, the core having a shading ring 19 on one limb to produce a torque in disc 6 when coil 18 is fed with A.C. which opposes the torque produced by fluid flow. One vane of disc 6 carries a contact 22 (Fig. 5) co-operating with fixed, insulated contacts 23, 24 projecting through the housing 1. The current through coil 18 is preadjusted to a value which makes the electromagnetic torque smaller than the aerodynamic torque produced by a required gas flow, whereby the disc 6 is rotated to make contact between contacts 22, 24, and a signal is sent via R 1 C 1 and amplifier 35 to the control unit, which increases the current through coil 18 and causes contacts 22, 24 to part. Thus the disc 6 oscillates as contacts 22, 24 make and break. The average value of the currents in coil 18 during oscillation is proportional to the rate of fluid flow. If the fluid flow is excessive, contacts 22, 24 do not subsequently break, and the signal through R 1 C 1 also passes through R 2 C 2 , which has a much higher time constant, to energize an alarm circuit 39. Low gas flow is indicated by an alarm circuit 36, energized when the balancing current in coil 18 is low. The Specification relates the materials required to make the apparatus particularly suitable for monitoring the flow of cooling gas in a fuel channel of a nuclear reactor.
