Fluid leak alert system
First Claim
1. A method for detecting unintentional flow of fluid through a fluid flow line, comprising:
- determining a length of time that fluid flow is present within a fluid flow line;
comparing the length of time that fluid flow is present to a prescribed maximum flow interval duration; and
outputting an alert in response to determining that the length of time that fluid flow is present is greater than the prescribed maximum flow interval duration.

Abstract
A fluid leak alert system comprises a flow sensor and a timer apparatus. The flow sensor is configured for sensing presence of fluid flow through a fluid flow line. The timer apparatus is connected to the flow sensor. The timer apparatus compares a prescribed maximum flow interval duration to a length of time over which the presence of fluid flow through the fluid flow line is sensed for determining if the length of time that fluid flow is present is greater than the prescribed maximum flow interval duration. The timer apparatus outputs an alert signal when the length of time is greater than the prescribed maximum flow interval duration. The timer apparatus includes a flow interval duration adjuster for enabling the prescribed maximum flow interval duration to be selectively set to any one of a plurality of different prescribed maximum flow interval durations.

16. A fluid leak alert system, comprising:
-
a flow sensing unit including a body and a flow sensor connected to the body, wherein the body is configured for being connected in series with a fluid flow line for enabling fluid from the fluid flow line to flow through the body and wherein the flow sensor is configured for sensing presence of fluid flow through body; a timer unit connected to the flow sensing unit, wherein the timer unit compares a prescribed maximum flow interval duration to a length of time over which said presence of fluid flow through the fluid flow line is sensed for determining if the length of time that fluid flow is present is greater than the prescribed maximum flow interval duration and wherein the timer unit includes an audible output device that outputs an audible alert when the length of time is greater than the prescribed maximum flow interval duration. - View Dependent Claims (17)
