An autonomous water supply controller which comprises an electronic circuit, a flowmeter which measures minimum liquid flows, a magnet and a magnetic sensor for measuring the current flow. It also comprises a hydraulic electrovalve and a turbidity sensor allowing detection of the impurity levels in the water. It also comprises an air sensor which prevents the controller from measuring when air flows therethrough. In addition there is a theft sensor which emits a locating radio signal when changes in the position of the controller are detected. Likewise there is a pressure sensor which includes a barometric pressure sensor enclosed inside a cavity in the lid of the mechanical section, said sensor, upon detecting an increase in pressure inside this cavity, sending this information to the microcontroller, which determines the pressure of the water flowing through the controller. All the parts mentioned are contained in a compact unit with dimensions similar to those of the water meters commonly available in the market, thereby reducing the costs of installing the controller in the location where the meter to be replaced is situated.
