Fluid flow measuring and control devices and method

A fluid flow measuring and control device for installation within plumbing channeling fluid, the device comprising:

• a main flow channelling system having an inlet and an outlet for connection to the plumbing;
• a bypass channelling system in parallel from the main flow channelling system, starting from a first location on the main flow channelling system and ending at a second location on the main flow channelling system downstream of the first location;
• a flowmeter 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;
• a valve for stopping the fluid flow in the main flow channelling system, hence blocking fluid flow in the fluid flow measuring device and in the plumbing;
• a first pressure sensor upstream of the valve and a second pressure sensor downstream of the valve;
• and
• a transceiver operatively connected to the flowmeter for collecting data therefrom and send the data to a computer, wherein the computer stores pre-recorded fluid usage signatures of specific appliances and compares the data to the pre-recorded fluid usage signatures for identifying in the data from the flowmeter that a specific appliance was used;
• wherein the computer is further adapted to at least one of:
• identify an abnormal fluid usage by comparing the data from the flowmeter from previously acquired data from the flowmeter;
• and
• identify an identity of the specific appliances which consume fluid;
• and
• wherein the computer is operably connected to the first pressure sensor, the second pressure sensor and the valve, to determine that there is abnormal usage and instruct the valve to close.
