Abstract
PURPOSE: To make it possible to perform economically the fine control of terminal pressure by controlling the exhaust pressure of a pump of water supply source on a basis of the water supply flow quantity in each terminal.
CONSTITUTION: Operator CAL uses flow quantity measured values, which are transmitted from water supply points 1 to 6, and a constant, which is determined by the structure of a pipe water supply equipment, to calculate enough exhaust pressure of a pump to sypply water at a prescribed terminal pressure in respective water supply points 1 to 6, and the maximum volue is selected and is properly overaged and is outputted in steps as required and is given to exhaust pressure controller PC as a set value.
