This invention concerns the measuring and water supply control system which consists of an electronic central water meter, the central unit, and water flow sensors. The advantage of this invention is that it eliminates any water leak (not a drop of water is lost) and consequently any economic and ecological damage, both at home and in major urban and hotel complexes, as well as the accurate, prompt, safe and economical measurement of consumption via telemetry. The measuring and water supply control system operates as follows: the central unit receives the signals of the electronic water meter as well as the water flow detectors. When the main unit receives these two signals at the same time then it considers that there is no leak and only keeps count of the electronic water meter. When the central unit receives a signal only from the electronic water meter then it considers there is a leak and instructs the solenoid valve to close the supply. In this way we achieve the annihilation of any leak.
