FloSure TR7 AICD A levitator ??Bernoulli Sum of Static Pressure, Dynamic Pressure and Friction loss along a streamline is constantThree forces are acting on the discFmom = Force due to momentumFlift = Force due to hydraulic liftFdrag = Force due to viscous drag

The disc will levitate (hover) and control flow depending on fluid rate, viscosity and densityLow viscosity reduces friction pressure and increases lift

High viscosity oil increases friction pressure pushing the disc away from the seat and thereby increasing oil flowLow viscosity and dense water reduces friction pressure and increases velocity thereby sucking the disc against the seat thereby restricting water flow Low viscosity gas reduces friction pressure and causing very high velocity thereby sucking the disc against the seat thereby restricting gas flow
