ABSTRACT:
A sheet with inlet and outlet ports forms a housing, with a flow tube disposed between the ports. In a preferred embodiment, a plurality of arms affixed at one end to the housing are adjustably spaced by a threaded tapered nut which mates with the other end of the arms. The flow tube passes between the arms and is constricted by the arms as the nut is advanced. The thread pitch, the degree of taper, and the point where the tube crosses the arms all determine the rate of constriction. In a further preferred embodiment the tube passes through a transverse indentation in the arms and is bonded thereto. In another preferred embodiment the housing is adapted to removably mount on an automatic flow sensing and adjusting module, which engages the tapered nut to adjust the flow rate through the tube.
