Abstract
There is described a fluid flow measuring and control device for installation within plumbing. The device comprises a main flow channelling system having an inlet and an outlet for connection to the plumbing, and a bypass channelling system in parallel from the main flow channelling system. A flowmeter is provided in the bypass channelling system for measuring the fluid flow in the bypass channelling system and thereby estimating the fluid flow at the inlet or at the outlet of the main flow channelling system. The flowmeter may comprise a wheel and a pair of movement sensors. A valve such as a solenoid valve can be provided as an on/off control for the plumbing. Using a microcontroller, the device can identify which appliance is used and determine consumption, or detect abnormal use or leaks and close the valve and/or notify a user mobile device.
