Abstract: A flow generator 21 for a respiratory therapy system configured to deliver a breathable gas flow to a patient comprises a housing 27 comprising an inlet 28 and an outlet 25 and a gas flow path between the inlet 28 and outlet 25. An impeller is mounted within the housing 27 for rotation about an axis, the impeller configured to be rotationally driven by a motor to provide a gas flow along the gas flow path. Various embodiments are disclosed in which the flow generator 21 further comprises a sensor 23 mounted in the housing 27 in the gas flow path and configured to detect a property of the gas flow. The sensor 23 may be mounted in the outlet 25 so as to project into the gas flow path. Flow generator may comprise an axial inlet 28 and a tangential outlet 25. In another embodiment the sensor 23 may be mounted in the inlet 28.

Abstract: A linear variable differential pitot tube includes a primary solenoid, a first secondary solenoid, a second secondary solenoid, wherein the primary solenoid is positioned in between the first secondary solenoid and the second secondary solenoid, wherein the first secondary solenoid and the first secondary solenoid have identical geometries, and a high permeability magnetic core, the high permeability magnetic core being structured to move relative to the primary solenoid, the first secondary solenoid, and the second secondary solenoid. Also, a system and method for measuring the localized velocity of a flow of a fluid using the linear variable differential pitot tube.

Abstract: A fluid flow device that can measure and control a flow of a fluid is described. Various procedures, including measuring, controlling, balancing, or calibration procedures can leverage differential pressure measurement. These differential pressure measurements can be measured across the fluid flow device such that a first pressure measurement is taken upstream of the fluid flow device while a second pressure measurement is taken downstream of the fluid flow device. Moreover, one or more of the various pressure measurements, and in particular the downstream pressure measurement, can be performed at stagnation zone where the flow has stagnated. Such can provide significant amplification and/or turndown capabilities.
