ABSTRACT:
The present invention relates to an optical sensor apparatus (21) for use in a remote meter monitoring system (20) for remotely monitoring the dials (34) of a utility meter or the like by use of a liquid crystal display (31). The liquid crystal display (31) includes five distinct areas 71 through 75 arranged in a semicircle in register with the circumferential path of a dial pointer arrangement (36) of the meter which including a dial pointer (37) and a disk like member (38) having a light absorptive semicircular portion (38a) and a reflective semicircular portion (38b). A sixth distinct area (76) being positioned in a diametrically opposed semicircle. The disk like member (38) being illuminated by a light emitting diode (40). The sixth distinct areas (71 through 76) being sequentially switched to a transparent condition and a readout of the light passing therethrough being obtained from a photodiode detector (42) so as to ascertain the angular position of the dial pointer arrangement (36) and thus obtain a readout thereof.
