System for monitoring leak of liquid flowing through piping network for every monitor area

Abstract

PURPOSE: To find a leak of a water supply or others automatically in unmanned service and to take a countermeasure such as alarm transmission by dividing the liquid piping network into plural monitor areas, providing a flow rate sensor with a flow rate signal transmitting function in piping in each area, and providing an inspection device with a monitor signal transmitting function in each area. CONSTITUTION: Each of dwelling multistory dwelling units is regarded as a monitor area, the flow rate sensor 11 with the flow rate transmitting function is fitted to a branch water pipe from water piping 7, and a presence/absence state is judged by inputting the signal of a card reader 13 fitted to an entrance door 6 to a controller 14 installed in a superintendent office. When a presence signal is inputted from the card reader 13, the flow rate sensor 11 is placed in a non-monitor state, but when an absence signal is inputted, the sensor is placed in a monitor state. If a flow rate signal is inputted from the flow rate senor 11 in the monitor state, it is judged that there is a leak or that a faucet is left open forgetfully, etc., and while an alarm is generated, a shut-off 12 valve is closed.
