Abstract:
1. A meter register, comprising: a register body having a rotatable drive shaft coupled thereto, a drive magnet attached to the drive shaft, at least one wheel co-acting with the drive shaft, the wheel having a first surface and an opposite second surface, and a reflective surface and a non-reflective surface on the second surface of the wheel; a plurality of optical emitters in facing relation to the second surface of the wheel and spaced about an axis which the wheel rotates, wherein the emitters are adapted to emit radiation on the reflective and non-reflective surfaces; and a single sensor mounted in facing relationship to the second surface of the wheel, wherein the plurality of emitters are between the second surface of the wheel and the sensor, the sensor adapted to co-act with reflected radiation from the reflective surface, whereby in operation when the drive shaft rotates, the wheel rotates about the axis and one or more emitters emit radiation that is reflected from the wheel to the sensor for a determination of flow through the meter and direction of flow.
