Abstract
Abstract 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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
259 words
Apparatus for converting a standard meter, having a plurality of rotatably driven dial elements indicating total units of a utility measured by said meter, into a meter capable of being read from a remote location, said apparatus comprising magnetic means mounted on the single dial element of said meter which indicates the lowest whole unit of utility consumption measured, said magnetic means being mounted for rotation with said single dial element, a single magnetic field sensitive element fixedly mounted on said meter in proximity to said single dial element and positioned to register intermittently with said magnetic means as said single dial element is rotated to produce an electrical signal in response to each field interception during rotation of said single dial element, said magnetic means comprising at least one permanent magnet secured to said single dial element and positioned to produce one said electrical signal in response to the consumption of a single whole unit of utility consumed and indicated by said single dial element, signal processing means for receiving said electrical signals to produce a unit pulse indicative of each field interception of said sensitive element by said magnetic means, counting means for receiving and summing said pulses to indicate the total units of utility measured by said meter, storage means for receiving said total units of information of utility measured and storing the same in a memory bank for future information, and interrogator means for selectively interrogating said storage means for receiving and transmitting information as to the total units measured over a selected time period.
Claim 2
Dependent Claim
