Abstract: A double-rate flow controller including a means for permitting fluid flow at a first high-flow rate, a means for reducing the first flow rate to a second lower flow rate and a means for regulating the volume of water passing through the flow controller during the high-flow condition before the high-flow rate is terminated and the low-flow rate begins.

Abstract: A flow sensing and control arrangement by which a jet of line fluid is continuously directed across a flow line against a biased pressure responsive device which moves to initiate a control function upon diffusion of the jet when line flow occurs. In a preferred embodiment, the pressure-responsive device controls a valve, normally closed by the jet but which opens upon the presence of line flow to introduce an additive to the flow line.
