First Claim
Patent Images
1. An arrangement for displaying the reading of a meter at a location remote from said meter comprising:
- switching means at said meter adapted to alternately close one of a pair of circuits each time a measured volume of metered product passes through said meter;
a respective conductor connected to each of said circuits and extending to said remote location;
a multidigit display unit;
counting means coupled to said display unit for causing said display unit to display digits corresponding to the contents of said counting means, said counting means having a count input and a reset input, said counting means responding to a count signal at said count input for incrementing its contents and responding to a reset signal at said reset input for setting its contents to a predetermined value;
pulse means coupled between said conductors and said count input for generating said count signal; and
fault detection means coupled between said conductors and said reset input for generating and thereafter maintaining said reset signal when neither of said circuits is closed.

Abstract
A remote meter display unit is connected to a meter index through a magnetically actuated single pole double throw switch cooperating with a magnet mounted on an index pointer shaft. The remote display unit is configured to increment a counter whenever the switch toggles. If the switch or any of the wires connected thereto are disconnected or shorted, the display is reset and maintained at zero. A portable reset/preset unit mates with the remote display unit and includes switches for resetting the remote unit and entering any desired number into the display.
