Abstract
Abstract A household fluid flow-rate monitor and control system is provided to prevent flood damage, fluid leakage and loss of fluid. The system includes a plurality of alarm units for monitoring fluid flow in the system; an automatic electrically operated valve for shutting off the fluid flow to prevent damage; a fluid meter for sending to a monitor an electrical signal for every unit of fluid flowing through the system; and a controller unit including a microprocessor unit and a memory unit connected to the automatic valve to shut off the system. The monitor receives input from the fluid meter or from a flood sensor and sends alarm signals for several types of events, such as burst flow, leakage, flood, etc. to the controller unit. The unit also has a manual override switch to bypass the electronics.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
130 words
1 . A househould fluid flow-rate monitor and control system to prevent flood damage, fluid leakage and loss of fluid, comprising: a) a plurality of alarm units for monitoring fluid flow; b) an automatic electrically operated valve for shutting off the fluid flow to prevent damage; c) a fluid meter for sending to a monitor an electrical signal for every unit of fluid flowing through the system; d) a monitor for receiving input from said fluid meter or from a flood sensor and for providing alarm signals for several types of events, such as burst flow, leakage, flood, etc. to a controller unit; and e) a controller unit including a microprocessor unit and a memory unit connected to said automatic valve to shut off the fluid flow in the system.
