ABSTRACT:
A fluid supply pressure control apparatus for use in conjunction with a pressure control valve (10) of a fluid supply system is disclosed which includes: first sensor means (26, 28) for sensing the pressure of the fluid at a first point (12, 14) in the system, and first control means (16) for controlling the pressure control valve (10) to adjust the pressure of the fluid at the first point in the system in accordance with a difference between the pressure sensor by the first sensor means and a predetermined pressure valve. The apparatus further includes second control means (24) for controlling the predetermined pressure value to reduce fluctuations in the fluid pressure at a second point in the system.
The aim of this apparatus is to maintain the lowest possible pressure in the supply pipes commensurate with maintaining a reasonable pressure in outlying and elevated areas and with meeting the demand for water. This provides a means of controlling water supply pressure whereby water loss through leakage is likely to be substantially reduced.
