Abstract

Reading device arranged at the outlet of a flowmeter for liquid, of the type consisting of four pistons arranged at 90º from each other, and joined on the unique support of a crankshaft driven in rotation and dragging a disk by means of a gear of a suitable relation one of whose wheels is integral with the crankshaft, the periphery of the disc carrying equidistant notches coated with a light-reflecting substance, which they buy from a light source to illuminate the peripheral region of the disk and means for measuring the rotation angle of the disk, said means comprising at least one photoelectric diode connected to a counter by means of an electronic circuit, characterized in that the light source is arranged perpendicular to the plane of the disk, illuminates its peripheral part, more particularly the notches and is located at equal distance over the circumference of the disc defined by the notches between two photoelectric diodes are visible in the reflected light, and in that the outputs of the two photoelectric diodes are connected to the respective inputs of the electronic circuit comprising a bistable scale and a fitness circuit which is sensitive to single-polarity pulses.
