Abstract:
A mechanism for forming a flow-indicating device, comprising:a shaping block adapted to operably engage a tubular body having opposed ends, one of the ends being a downstream end, so as to form a constricted portion therebetween, the body being adapted to direct a flow therethrough and adapted to have a flow element disposed therein, the constricted portion of the body formed by the shaping block thereby defining a constricted orifice having a downstream side, the constricted orifice being configured to prevent the flow element from passing therethrough and having the flow element disposed on the downstream side thereof, the shaping block being further configured with respect to the body such that the flow element engages the constricted orifice when the flow is below a flow rate and moves toward the downstream end of the body as the flow increases over the flow rate to thereby indicate the flow through the body.
