ABSTRACT:
A meter for remote inspection having a wheel assembly which enables a counting number indicating the amount of consumption of a measuring object, such as electric energy, or city water or the like to be remotely inspected in a remote inspection center equipped with computer systems. The wheel assembly comprises a plurality of wheels representing respective decimal columns, a series of pinion wheels for transmitting a driving torque, detecting means for detecting the binary-coded signal of a counting number including four photo-sensor portions, and fixed disk means for mounting the detecting means. A predetermined one of side surfaces of some wheels is composed of ten zones which are uniformly divided and selectively colored by two kinds of colors to provide the binary-coded signal of each order of decimals of the counting number. The fixed disks are disposed non-rotatably on an axle of the wheel assembly between the wheels, and mounted with the photo-sensor portions on the side surfaces thereof opposite to the colored side surfaces of the wheels. The photo-sensor portions detect the binary-coded signal of each order of decimals of the counting number from the colored side surfaces of the wheels when positioned adjacent thereto.
