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.
Claims11
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.
