Abstract

PURPOSE: To enhance accuracy of control by feeding a regulator with the value of sensed discharge pressure of a pump which shall be however subtracted by the preset value.
CONSTITUTION: Line loss is from a calculator 3 into a regulator 13 connected to a controller 9, and the discharge pressure of a pump sensed off by a sensor 8 is, at a calculator 12, subtracted by a preset value set by a setting device 5. The result shall be input so the regulator 13. According, the change in rate of flow is input to the regulator, to that the accuracy of controlling can be enhanced.
