Abstract
A snap-action flow interrupt device for terminating flow into a cryogenic storage container utilizes the momentum of the incoming liquid spray as a means of maintaining a float in a submerged position until the proper liquid level is attained. The incoming spray of liquid exerts a downward impact force on a surface of the float. The rising liquid level exerts an upward and increasing buoyant force on the float. When the rising liquid in the tank disrupts the spray, the buoyant force snaps the float upwards to interrupt the flow of liquid. The abrupt motion of the float generates a pressure spike and flow reduction, either of which may be easily detected by automatic fill termination devices or by a human operator.
