Abstract

A method and apparatus for coupling a meter register to a communication device such that output data signals from the meter register can be transmitted to a remote location. The coupling arrangement includes a data transfer wire that is connected to the meter register and is inductively coupled to the communication device such that the data transfer wire does not need to be conductively connected to the communication device. During installation of the communication device, the inductive coupling between the data transfer wire and the communication device eliminates the requirement of a conductive connection.

Claims

1. A system for transmitting consumption measurement data from a utility meter to a remote monitoring location, the utility meter having an electronic meter register operable to accumulate data related to the flow of a commodity through the utility meter, the accumulated data being represented by an output data signal, the system comprising:

a data transfer wire conductively connected at a first end to the electronic meter register for receiving the output data signal, a second end of the data transfer wire including a first inductive coil enclosed within a connector module; and

a communication device inductively coupled to the data transfer wire for receiving the output data signal and transmitting the accumulated data to the remote monitoring location, wherein the communication device includes a receptacle port sized to receive the connector module, the receptacle port being generally aligned with a second inductive coil contained within the communication device, wherein the first inductive coil of the connector module is electrically spaced from the second inductive coil when the connector module is received in the receptacle port.

2. The system of claim 1 wherein the first inductive coil of the connector module is positioned behind a front face surface of the connector module and the second inductive coil of the communication device is positioned behind a front wall and aligned with the receptacle port, wherein the front face surface contacts the front wall when the connector module is received within the receptacle port.

4. The system of claim 1 wherein the first end of the data transfer wire is electrically connected to the meter register.

5. The system of claim 1 wherein the first inductive coil is inductively coupled to the second inductive coil such that the output data signal can be transferred from the first inductive coil to the second inductive coil.

6. The system of claim 1 wherein the communication device includes a plurality of receptacle ports such that the communication device can receive a plurality of data transfer wires from a plurality of electronic meter registers.

7. The system of claim 1 wherein the receptacle port includes a pair of flexible fingers that engage the connector module to hold the connector module within the receptacle port.
