description The utility model provides a remote metering device and a counter reading circuit thereof. The counter reading circuit comprises a digit wheel, a plurality of groups of photoelectric sensors, and a single-chip microcomputer connected with the photoelectric sensors. The digit wheel comprises a plurality of counter wheels on different digits. Each group of the photoelectric sensors is corresponding to one counter wheel. Each photoelectric sensor comprises a luminotron and an optical receiving tube, wherein each group of photoelectric sensors comprise two photoelectric sensors, and the two photoelectric sensors are connected in parallel. The remote metering device and the counter reading circuit have the advantages of low cost, accurate data sensing, reliable performance, low operating failure rate, etc.
