A digital multi range liquid level detector to verify and maintain a predetermined level in a container. The level is measured by a capacitive sensor located above or in the liquid to be maintained. The capacitive sensor is composed of a pair of probe connected to a signal converter chip to obtain a digital data. The digital data is then compared to a reference value obtain during the initial calibration. The present invention is composed of two paired components, a capacitive digital sensor and a fluid control valve that can be installed at different locations. The sensor determines the liquid level and then transmits the acquired data to the fluid valve control receiver via wire or radio frequency (RF). The sensor and valve are programmable in order to evaluate different possibilities such as water level, water activities and recurring low level demands. They can also be reprogrammed.
