Classification: CPC B  E | IPC B  E

Claim 0:
1. An apparatus for generating foam, comprising:
a fluid in-flow manifold in fluid communication with a source of liquid to be foamed, the fluid in-flow manifold comprising a pressure sensor in fluid communication therewith;
a plurality of branch lines in fluid communication with the fluid in-flow manifold at an inlet of each branch line and in fluid communication with a foam out-flow manifold at an outlet of each branch line, each branch line comprising a branch line flow control valve, a Venturi tube and in fluid communication with a throat of each Venturi tube an air induction control valve, the foam out-flow manifold comprising a pressure sensor in fluid communication therewith;
at least one in-flow control valve disposed between the source of liquid and the in-flow manifold; and
at least one out-flow control valve in fluid communication with the fluid out-flow manifold, whereby the branch line flow control valve on each branch line, the air induction control valve on each branch line, the at least one in-flow control valve and the at least one out-flow control valve are operable to provide a chosen flow rate of the liquid into the in-flow manifold, a selected foam product flow rate out of the out-flow manifold and a selected density of the foam product.
