Pressure sensor for determining fluid velocities

摘要: A fluid-measuring system comprising an orthogonal velocity sensor utilizing fluid pressures which can be adapted for use in flight or mobile fixed installations. The comprises a probe that is internally divided into four compartments with the longitudinal axis at right angles to plane of measurement, and sensing ports oriented proper relationship sense directions moving past sensor. By measuring pressure differences between chambers on opposite sides probe, using suitable instrumentation relative airspeed determined.
