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.

A linear variable differential pitot tube, comprising:
- 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 second 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;
- and
- a cylindrical housing having a wall and an inner bore, wherein the primary solenoid, the first secondary solenoid, and the second secondary solenoid are provided within the wall, and wherein the magnetic core is movable linearly along a longitudinal axis of the housing within the bore, wherein the longitudinal axis defines a flow direction through the housing, wherein the housing includes:
- (i) a static inlet provided in the wall adjacent a first end of the housing, the static inlet having a longitudinal axis that extends transversely to the longitudinal axis and the flow direction through the housing, and (ii) a stagnation pressure inlet provided at a second, terminal end of the housing opposite the first end of the housing, wherein the stagnation pressure inlet comprises an axial opening about the longitudinal axis of the housing that faces and is aligned with the flow direction through the housing, and wherein the primary solenoid, the first secondary solenoid and the second secondary solenoid are positioned in between the static inlet and the stagnation pressure inlet.
