The present invention relates to a meter register having an encoder for measuring material flow. According to the invention, the meter register comprises 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. Using a plurality of optical emitters and a sensor adapted to co-act with reflected radiation from the reflective surface, a determination of flow through the meter and direction of flow can be established. |
