Patent ID: 8193942

Claim:
A method of detecting flow in a fluid source, said method comprising the steps of: disposing a processor in a housing configured for being associated with a fluid source; electrically associating a memory with said processor and configuring said memory to store alert-criteria and flow-criteria; electrically associating a flow sensor with said processor and configuring said flow sensor to detect fluid flow through said fluid source; electrically associating an environment sensor with said processor and configuring said environment sensor to generate environment sensor signals related to an environmental parameter; electrically associating a sound generator with said processor and configuring said sound generator to generate a sound based alert; electrically associating a visual signal generator with said processor and configuring said visual signal generator to generate a visual based alert; configuring said processor to use said flow sensor and said flow-criteria to detect a predefined flow condition; and configuring said processor to activate at least one of said sound generator and said visual signal generator according to said alert-criteria for the detected flow condition.
