Abstract
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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
173 words
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. ,
Claim 2
Dependent Claim
173 words
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. ,
Claim 3
Dependent Claim
30 words
The arrangement according to Claim 1 wherein said fault detection means is further effective to generate and thereafter maintain said reset signal in the event both said circuits are closed.
Claim 4
Dependent Claim
65 words
The arrangement according to Claim 1 wherein said switching means includes a single pole double throw switch having a moveable pole and two fixed contacts and wherein said conductors include a respective conductor connected to said pole and each of said contacts, said arrangement further including a source of voltage coupled to said pole conductor and said pulse means is connected to said contact conductors.
Claim 5
Dependent Claim
35 words
The arrangement according to Claim 1 wherein the meter includes a proving circle rotating on a shaft and said switching means includes a radially polarized circular magnet mounted axially on said shaft for rotation therewith.
Claim 6
Dependent Claim
26 words
The arrangement according to Claim 1 further including manually controllable reset means for resetting said fault detection means to terminate the generation of said reset signal.
Claim 7
Dependent Claim
32 words
The arrangement according to Claim 5 further including count setting means coupled to said counting means for providing the facility for manual entry of a predetermined count content into said counting means.
Claim 8
Dependent Claim
65 words
The arrangement according to Claim 6 wherein said reset means and said count setting means are both included within an enclosure which is portable with respect to said remote display unit, said remote display unit including a connector coupled to said fault detection means and said counting means and said'portable enclosure including a connector adapted to mate with the connector of said remote display unit.
Claim 9
Dependent Claim
23 words
The arrangement according to Claim 7 wherein all power for said portable enclosure is supplied by said remote display unit through said connectors.
Claim 10
Dependent Claim
27 words
The arrangement according to Claim 8 wherein said count setting means includes a plurality of digital switches through which an operator may set said predetermined count content.
Claim 11
Dependent Claim
40 words
The arrangement according to Claim 9 wherein said portable enclosure includes a switch selectively closable by an operator and said reset means includes means responsive to closure of said switch for generating a pulse to reset said fault detection means.
Claim 12
Dependent Claim
99 words
The arrangement according to Claim 10 wherein said count setting means includes: a down counter; means responsive to said pulse for setting said down counter with the count established by said digital switches; a counting pulse generator; means responsive to said pulse from said reset means for enabling said counting pulse generator; means responsive to counting pulses from said counting pulse generator for decrementing said down counter; means responsive to the contents of said down counter reaching zero for disabling said counting pulse generator; and means for transmitting said counting pulses to the count input of said counting means.
