Abstract

709,071. Rotary meters. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. Aug. 8, 1951, No. 18703/51. Class 110(2) Means for calibrating a meter 3, by comparison with a standard meter 2, comprises speed-indicating means. preferably stroboscopic, and a valve 18 in a by-pass 17. around the meter 2, the degree of opening of the valve being shown. Large and small flows of liquid flow through a pipe 1 from a mains or storage tank respectively, under control of a threeway valve. The meter 2 drives a disc carrying a ring of reflectors, or a disc surmounted by a mirror and fitted with a ring carrying a series of distributed apertures. The meter 3 drives a similar device. A light ray 11, passes through an optical system 10 and the reflections pass through a lens 12 on to a mirror 13 and through a lens 14 on to a disc having a stroboscopic action. When the stroboscopic disc appears stationary, there is a fixed ratio between the meter speeds, and adjustment of the meter 3 is made to secure this effect. An arrow 19 gives the degree of opening of the valve 18.
