Image Description -  0660-2

A schematic drawing is labeled “Figure 2. Flo-Fuse Typical Diagram.”

The upper half of the drawing is labeled “OPERATION DURING RATED FLOW.”
It depicts fluid passing through an open Flo-Fuse.  A hollow box depicts 
the Flo-Fuse with a “MEDIA INLET” tube on the left side and an “OUTLET”
tube on the right side.  Arrows indicate the motion of the fluid through
the Flo-Fuse.  A conical structure is shown between the “MEDIA INLET”
tube and the “OUTLET” tube.  The apex of the cone points toward the
“OUTLET” tube and is coaxial with it.  The cone does not protrude into
the “OUTLET” tube.

The lower half of the drawing is labeled “AFTER SENSING DOWNSTREAM
RUPTURE.”  It depicts fluid flow being blocked by a closed Flo-Fuse.
In this case the cone is shown farther to the right and protrudes into
the “OUTLET” tube effectively blocking it.
