Improvements relating to remote indicating systems

930,191. Rotary meters. ROTRON CONTROLS CORPORATION. Nov. 14, 1960, No. 39040/60. Class 110 (2). [Also in Group XXIV] A system for remotely recording and indicating the liquid flow through a rotary flowmeter F, Fig. la, of the vortex velocity type, comprises a Selsyn transmitter 1, Fig. 1, connected to the flowmeter rotor by a magnetic pick-up and to a Selsyn receiver 2 driving through gearing 3, 4, a worm-screw 5. The worm-screw 5 co-operates with an idler wheel 6 carried in a casing 61 having a finger 31 which moves to release pressure on a spring-loaded plunger 30 to adjust the position of a potentiometer 29 and towards a switch 24. On the switch 24 being contacted, a variable speed motor 9 begins to operate, and through a sprocket drive 10, 101 rotates a cone 15 to frictionally drive a roller 16 urged by a spring 20 into engagement with the cone. The roller 16 through a gear train 21, 22, 23 drives a worm-screw 7 to move the casing 61 in a direction opposite to its original direction. The motor 9 is also connected to a motor controller 25 and through the positioning of the potentiometer 29, the voltage imput to the motor 9 is varied to vary the motor speed in accordance with flow through the flowmeter. The worm-screws 5, 7 rotating in opposite directions maintain the casing 61 stationary under steady operating conditions. Any variation in flow will result in the re-positioning of the casing 61 with a corresponding adjustment of the speed of the motor 9. The motor 9 also operates through a belt-drive 62, a flow rate indicator 63, through a sprocket drive 71, a total flow indicator 68 and through a sprocket drive 66, a ticket printer 65. The cone 15 slidably mounted on a shaft 13 co-operates with a yoke fitting 43 movable by a screw 45 to adjust the position of the cone to establish a desired meter factor or apply any other corrections. The yoke is movable through a gear train 53, 52, 50, 49 on the closing of a reversing switch 47 to drive a reversible motor 46. The meter factor is recorded on an instrument 57 driven by the motor 46 through the gearing 49, 50 and a sprocket drive 56.
