Abstract
Apparatus for achieving liquid flow at constant discharge rate from a liquid reservoir wherein the surface of liquid therein fluctuates in elevation.
Claims7
Liquid flow control apparatus for use in a reservoir of liquid of fluctuating level comprising a buoyant float member, an intake weir element carried by said float member, a conduit having one end thereof communicating with said weir element and extending downward therefrom to conduct flow by gravity of liquid from the weir, said conduit being yieldable to accommodate movement of said weir and float member, and counterbalancing springs which counterbalance the change in buoyancy as the buoyant float member and connected conduit rise and fall with the variable elevation of the liquid in which disposed.
A method for achieving liquid flow at constant discharge rate from a liquid reservoir wherein the surface of liquid therein fluctuates in elevation which comprises
- positioning on the surface of the liquid in said reservoir a buoyant float member which carries an intake weir element,
- connecting one end of a yieldable conduit to said weir,
- positioning the conduit to be submerged in the liquid in the reservoir and with the distal end of said conduit outside of said reservoir at an elevation lower than said weir whereby liquid flows from said weir through said conduit by gravity,
- securing counterbalancing springs to said buoyant float member whereby the springs automatically counterbalance the change in buoyancy as the buoyant float member and conduit rise and fall with the elevation of the liquid in which disposed.
