ABSTRACT:
An electronic remote reading system for a meter is disclosed, consisting of a permanent magnet on a shaft, rotating in proportion to volume passing through the meter. A switch, sensitive to a magnetic field, mounted on the outside of the meter in the influence of the magnetic field, a low current consumption circuit connecting the switch to a remotely located counter, powered by an energy source, such as alkaline batteries or a solar panel. The circuit is connected in such a manner that the power consumed is of such a small magnitude that the alkaline batteries have a life essentially equal to their shelf life. The solar panel is of a physical size to be mounted directly as part of the counter housing.
