Abstract

A meter register includes a register body having a rotatable drive shaft coupled thereto. A drive gear is attached to the drive shaft and at least one follower gear is rotatably attached to the register body and coupled with the drive gear. An antenna is provided that includes a first electrically conductive sheet, a second electrically conductive sheet, and an axially extending leg electrically connected to the first electrically conductive sheet and the second electrically conductive sheet. A first electrically conductive sheet is spaced an axial distance away from the second electrically conductive sheet wherein at least a portion of the register body is sandwiched between the first electrically conductive sheet and the second electrically conductive sheet. The meter register can be attached to a meter body and, further, an auxiliary antenna can be attached to the meter register. Also disclosed is a method of operation of a utility measuring system that incorporates the above-described meter register.

a sealed register body having a face portion and a body defining an internal cavity;

a rotatable follower magnetic member provided in said internal cavity, said follower magnetic member adapted to be rotated by a driving magnetic member external of said sealed meter register, said follower magnetic member provided within said internal cavity;

an antenna provided within said internal cavity, and a visual display provided within said internal cavity and visible through said face portion; and

a microprocessor coacting with said antenna, wherein said rotatable member coacts with said microprocessor to determine a volume of flow and/or a flow rate through a meter and wherein said antenna is adapted to transmit a signal identifying the flow rate and/or the volume of flow measured by said register, and wherein said visual display displays a volume of flow measured by the register that corresponds to a number of rotations of said rotatable member.

2. A meter register as claimed in claim 1, wherein said visual display is an odometer.

3. A meter register as claimed in claim 1, further comprising a sensor coacting with said follower magnetic member and said microprocessor, said microprocessor corresponds rotations of said follower magnetic member to a flow rate and/or volume of flow measured by the register.

4. A meter register as claimed in claim 3, wherein said rotatable member comprises a rotatable drive shaft having a first end attached to said follower magnetic member and a drive gear attached to said shaft.

5. A meter register as claimed in claim 4, further comprising an odometer coupled to said drive gear.

7. A meter register as claimed in claim 4, further comprising a sensing follower gear rotatably secured to said body and coacting with said drive gear, said sensing follower gear rotates about a sensing axis and a sensing magnet coacting with said sensing follower gear and radially spaced from the sensing axis whereby when said sensing follower gear rotates about the sensing axis, said magnet rotates about the sensing axis in a rotating plane, and a first magnetically activated switch attached to said body spaced an axial distance from said rotating magnet plane, whereby when said magnet and said first magnetically activated switch are radially aligned, said first magnetically activated switch is in a first state and when said magnet is not radially aligned with said first magnetically activated switch, said magnetically activated switch is in a second state.

8. A meter register as claimed in claim 7, further comprising a second magnetically activated switch attached to said body spaced an axial distance away from the rotating magnet plane, said second magnetically activated switch is spaced circumferentially from said first magnetically activated switch, whereby when said second magnetically activated switch and said magnet are radially aligned, said first magnetically activated switch is in a first state and when said magnet is not radially aligned with said second magnetically activated switch, said second magnetically activated switch is in a second state, and wherein said magnet is adapted to rotate relative to said first magnetically activated switch and said second magnetically activated switch, whereby depending on the position of said magnet either none, one, or both of said first magnetically activated switch and said second magnetically activated switch are activated and wherein as the magnet rotates about the sensing axis relative to said first magnetically activated switch and said second magnetically activated switch, a rotational direction of said sensing follower gear can be determined by monitoring a sequence of the first state and second state of said first magnetically activated switch and said second magnetically activated switch.

9. A meter register as claimed in claim 8, wherein said first magnetically activated switch and said second magnetically activated switch are reed switches.
