Abstract

A method for monitoring a fluid supply system includes detecting a fluid flow through the fluid supply system, and monitoring at least a length of time the fluid flow has flown without interruption, a total volume of the fluid flow that has flown, and a flow rate of the fluid flow in response to detection of the fluid flow.

Claims

1. A method for monitoring a fluid supply system, comprising the steps of:

a) detecting a fluid flow through the fluid supply system; and

b) monitoring at least a length of time the fluid flow has flown without interruption, a total volume of the fluid flow that has flown, and a flow rate of the fluid flow in response to detection of the fluid flow.

2. The method as recited in claim 1, comprising the step of:

c) shutting off the fluid flow in response to the length of time the fluid flow has flow without interruption exceeding a pre-defined maximum length of time.

3. The method as recited in claim 1, comprising the step of:

c) shutting off the fluid flow in response to the total volume of the fluid flow that has flown exceeding a pre-defined maximum flow volume.

4. The method as recited in claim 1, comprising the step of:

c) shutting off the fluid flow in response to the flow rate of the fluid flow exceeding a pre-defined maximum flow rate.

5. The method as recited in claim 1, comprising the step of:

c) periodically performing a leak test of the fluid supply system at a pre-defined interval of time.

6. The method as recited in claim 5, wherein said step c) includes the steps of:

shutting off the fluid flow;

measuring a system pressure associated with the fluid flow subsequent to the step of shutting off the fluid flow; and

issuing a warning signal in response to a pre-defined maximum percentage loss of the system pressure of the fluid flow.

7. The method as recited in claim 1, wherein said step b) includes the steps of:

selecting one of a plurality of user profiles associated with the fluid supply system; and

comparing each of the length of time the fluid flow has flown without interruption, the total volume of the fluid flow that has flown, and the flow rate of the fluid flow with a plurality of pre-defined parameters associated with the selected user profile.

8. The method as recited in claim 7, comprising the step of:

c) shutting off the fluid flow in response to at least one of the length of time the fluid flow has flown without interruption, the total volume of the fluid flow that has flown, and the flow rate of the fluid flow exceeding a maximum limit associated with one of the plurality of pre-defined parameters of the selected user profile.

9. The method as recited in claim 8, comprising the step of:

d) issuing a warning signal in response to shutting off the fluid flow.

10. The method as recited in claim 1, comprising the step of:

c) repeating said steps a) and b) in response to detection of zero fluid flow through the fluid supply system.

11. The method as recited in claim 1, comprising the step of:

c) programming a microprocessor with a plurality of predefined parameters related to the fluid flow.

12. The method as recited in claim 11, wherein said step c) is performed prior to said steps a) and b).

13. A method for monitoring a fluid supply system, comprising the steps of:

a) analyzing a usage pattern of a fluid flow associated with the fluid supply system for a predefined period of time;

b) automatically adjusting a plurality of system parameters in response to analyzing the usage pattern.

14. The method as recited in claim 13, wherein said step a) includes the step of:

recording real time fluid flow data associated with the usage pattern of the fluid flow for the predefined period of time.

15. The method as recited in claim 14, wherein said step b) includes the step of:

automatically adjusting the plurality of system parameters based upon the real time fluid flow data recorded during the predefined period of time.

16. The method as recited in claim 13, comprising the step of:

c) repeating said steps a) and b) in response to a change of a parameter associated with the fluid supply system.

17. The method as recited in claim 13, comprising the step of:

c) initiating a learn mode prior to said steps a) and b).

18. A method for monitoring a fluid supply system, comprising the steps of:

a) measuring real time fluid flow data of a fluid flow communicated through the fluid supply system;

b) comparing the real time fluid flow data with a plurality of predefined parameters; and

c) blocking the fluid flow in response to any portion of the real time fluid flow data exceeding a maximum limit associated with at least one of the plurality of predefined parameters.

19. The method as recited in claim 18, wherein the plurality of predefined parameters include at least a length of time the fluid flow has flown without interruption, a total volume of the fluid flow that has flown, and a flow rate of the fluid flow in response to detection of the fluid flow.
