Abstract
The paper describes the method that can be used to monitoring of a water feeding system of a civil building and its subsystems, using a graphic interface of a soft-ware pack – SCADA (Supervisory Control and data Acquisition), WinCC Flexible. The effective adjustment of the pressure of the water feeding system implies using specific elements: sensors, execution elements, programmable automatons and monitoring devices. In the paper, also is analysed the situation in which three centrifugal pumps are utilized as execution elements, a pressure sensor – to measure the pressure of the water feeding system of the consumer, three sensors that detect the presence of water in each well and a Siemens programmable automaton, from the SIMATIC S7-300 series, which controls the process and a PC for the acquisition of data and for monitoring. Thus, it presents a schematic system operating water supply, logic operation sequence control, protection, signage and display alarms
