Abstract

A method and apparatus for measuring a fluid and determining a leak comprising the steps of providing a meter and a meter register coacting with the meter. When a leak is detected, a signal is transmitted from the meter register regarding fluid consumption. The transmitted signal indicates a leak either when the measured flow rate remains a fixed volume over a fixed period of time, or the measured flow rate exceeds a threshold value.

Claims

1. A method of detecting a leak in a liquid consumption system, comprising the following steps:

providing a meter housing having a liquid inlet opening, a liquid outlet opening, a measuring chamber between, and in fluid communication with, the liquid inlet and the liquid outlet openings, and a cavity having an access opening;

providing a meter register in the access opening of the meter housing, wherein the meter register comprises a microprocessor and the meter register is coupled with the measuring chamber to coact with the measuring chamber to receive liquid flow information from the measuring chamber, wherein the microprocessor of the meter register receives the liquid flow information and measures the amount of liquid flowing through the measuring chamber as a function of time defined as a measured flow rate;

passing a liquid from a liquid source, through the liquid inlet opening of the meter, through the measuring chamber of the meter and through the liquid outlet opening of the meter to the liquid consumption system, wherein as the liquid moves through the measuring chamber, the measuring chamber generates the liquid flow information, and the microprocessor provides the measured flow rate;

generating a signal indicating a leak when the measured flow ate is greater than zero and when at least one of the following events occurs;

(i) the measured flow rate remains constant over a fixed period of time, or

(ii) the measured flow rate exceeds a threshold flow rate value; and

providing a transmitting element and a plurality of sensors coacting with a rotatable member, whereby when said rotatable member rotates about an axis, the transmitting element activates said sensors that send signals to said microprocessor to correspond said signals with a flow rate and/or flow volume measured by said meter register.

2. The method as claimed claim 1, further comprising the steps of transmitting information when said meter has been tampered with.

3. The method as claimed in claim 1, wherein the meter register is magnetically coupled with the measuring chamber and further comprising:

transmitting information when said meter has been tampered with, wherein said tampering comprises subjecting said meter register to a magnetic field above a threshold value.

4. A utility meter, comprising:

a meter body having a chamber through which material passes;

a measuring unit contained within said chamber, said chamber comprising a rotating member; and

a register attached to said chamber, said register comprising;

a register body having a rotatable drive shaft coupled thereto;

a metallic body attached to a clear face to form an internal chamber, said internal chamber receiving said register body; and

an antenna, comprising a first electrically conductive sheet, a second electrically conductive sheet, and an axially extending leg electrically connected to said first electrically conductive sheet, said first electrically conductive sheet spaced an axial distance away from said second electrically conductive sheet, a circular metallic ring mounting said metallic body, wherein said metallic ring is electrically connected to said first electrically conductive sheet by a cable to space said first and second electrically conductive sheets from said register body antenna.

5. The meter of claim 4, wherein said register transmits periodically or nonperiodically via said antenna signal identifying a meter code and utility consumption.

6. The meter of claim 5, wherein said signal identifies an actual flow rate corresponding to flow rate reading of said meter.

7. The meter of claim 6, wherein said meter issues an alarm if the flow rate exceeds a fixed flow rate or the flow rate does not change over a period of time.

8. A meter register, comprising;

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

a rotatable member provided in said internal cavity;

an antenna provided within said internal cavity, wherein the antenna comprises a first electrically conductive sheet, a second electrically conductive sheet, and an axially extending leg electrically connected to said first electrically conductive sheet, said first electrically conductive sheet spaced an axial distance away from said second electrically conductive sheet;

a visual display provided within said internal cavity and visible through said face portion, wherein said visual display displays a volume of flow measured by the rotations of said rotatable member; and

a microprocessor coacting with said antenna and said rotatable member, wherein said rotatable member coacts with said microprocessor to determine a volume of flow and/or a flow rate through a meter, and to generate a signal identifying the flow rate and/or the volume of flow measured by said register, wherein said microprocessor forwards the signal identifying the flow rate and/or the volume of flow measured by said register to said antenna, and wherein said antenna is adapted to transmit the signal identifying the flow rate and/or the volume of flow.

9. The meter register of claim 8, wherein said visual display is an odometer.

10. The meter register of claim 8, further comprising a sensor coacting with said rotatable member and said microprocessor, said microprocessor corresponds rotations of said rotatable member to a flow rate and/or volume of flow measured by the register.

11. The meter register of claim 10, wherein said rotatable member is a rotatable follower magnetic member and rotatable follower magnetic member comprises a rotatable drive shaft having a first end attached to said follower magnetic member and a drive gear attached to said shaft, and wherein said drive gear coacts with said visual display to display a volume of flow measured by the rotations of said rotatable member.

12. The meter register of claim 8, further comprising a detection switch for detecting tampering of said register, whereby when said tampering switch is activated through tampering a fixed period of time, said register emits a signal that said register has been tampered with.

13. The meter register of claim 8, further comprising an electrical power source contained within the internal cavity and electrically coupled to said microprocessor and providing electrical power to transmit signals from said antenna.

14. The meter register of claim 8, wherein said body comprises a metallic body, said metallic body attached to a clear face to form the internal cavity, said internal cavity receiving said register body and said clear face forms said face portion.
