Abstract
A gas meter using optical communication. The meter includes a shaft that is rotated by a flow of gas, a first sensor for sensing a first rotational angle of the shaft, a second sensor for sensing a second rotational angle of the shaft, a first light source operated by the first sensor for issuing a first light signal, and a second light source operated by the second sensor for issuing a second light signal. One or more fiber optic cables carries the light signals to an external meter interface having an optical receiver. A rotation of the shaft is recognizable by the external receiver when first one then the other of the light signals is detected.
