发明名称 Electronic remote meter reading apparatus
摘要 A meter reader assembly is adapted for mounting on a standard utility meter having a plurality of rotating dial elements for visually indicating total units of the utility consumed. The assembly includes a magnetic reed switch fixedly mounted adjacent the single meter dial element which indicates the lowest whole unit of utility volume consumed, and one or more permanent magnets mounted on this single dial element in a position to traverse the reed switch each time the single dial element rotates through a distance to indicate the consumption of a single whole unit of utility. The reed switch opens and closes each time it is traversed by a magnet to produce an electrical pulse in a logic circuit which also contains a summing circuit for totalling the pulses, and a shift register memory. The logic circuit is electrically connected to interrogator means which interrogates the shift register memory and transmits the stored information received therefrom, as to total units measured by the meter, to a remote display or printout.
