Abstract
PURPOSE: To control so that the liquid level of the second vessel is constant, in receiving the liquid from the vessel having the opening at the bottom with the second vessel with similar construction and in supplying the liquid to supply through this opening.
CONSTITUTION: Liquid is fed in natural drop from the opening with variable sectional area from the first vessel V1 to the second vessel V2, and it is fed to demand from the opening of V2. To keep constant the supply flow, by adjusting the area of opening, the control of feed-forward can be made. On the other hand, since the sectional area S2 of V2 is sufficiently greater in comparison with that of the opening of V1, the response time constant at liquid level h2 with the opening sectional area varied is greater and the response idle time is small for W1 when the opening area is changed. So-called ON-OFF feedback control is suitable and the both controls are applied.
