This paper discusses the study of design and application of constant pressure water supply system, a way introduced to save energy and improve the quality of water supply. It talks about the problems with the old system and offers an introduction to the technology of automatic measurement of water level and protection measures. It also explains the general design proposal and software design about the constant pressure water supply system which adopts the combination of frequency conversion technology, PLC technology and automatic control technology. The practice proves that the system functions well and is able to save energy and greatly improve the quality of water supply and the operation reliability.
