Abstract
PURPOSE: To enable stoppage of an oil-feeding device by accurately detecting the abnormality of a signal-emitter which emits a pulse signal showing the quantity of oil-feeding in a liquid-feeding device in an oil station and the like.
CONSTITUTION: An emitting part P is constituted by a geared wheel 9 rotated by the output of a flowmeter and by a plurality of emitters 10 and 11 arranged near the geared wheel 9 and emitting flow-rate pulses A and A' corresponding to the quantity of oil-feeding. When an oil-feeding nozzle is removed from a case 3, a motor 6 is energized by a signal from a switch 4, while counting circuits 12 and 13 and operating circuits 14 and 18 are turned to bear zero. With the oil-feeding being started, the flowmeter measures the quantity of oil-feeding, the wheel 9 is rotated by the ouput thereof, and the emitters 10 and 11 emit the pulse signals A and A' corresponding to the passage of the teeth of the wheel 9. The signals A and A' are counted by the circuits 12 and 13 and the difference between the outputs from two circuits 12 and 13 is operated in the circuit 14. This difference is compared in a circuit 16 with the set value of an allowable difference setting circuit 17, and, when the difference exceeds the set value, a detection signal B is outputted and the motor 6 stopped by the signal B.
