Abstract

Disclosed is a method and probe for measuring the direction and force of gaseous of liquid flows in which two dynamic pressures are measured which are built up in two measuring chambers under the influence of the flow at a certain free-stream angle or a plurality of dynamic pressures are measured which build up in a plurality of measuring chambers under the influence of the flow at a certain free-stream angle, and wherein from the difference or the quotient of measured dynamic pressures or from absolutely or vectorially added measured values, the direction and/or the force of the flow is determined through mathematic processing. The measuring chamber openings are rectangular-shaped or slot-shaped, the center lines of a pair of measuring openings are positioned in a plane, and the arrangement of the measuring chamber openings relative to each other is fixed. The probe can also be used to measure the force of the flow. In one embodiment, the chambers are essentially located along an arc or along the periphery of a circle in which under the influence of currents, dynamic pressures are formed in the chambers. Measuring devices determine the pressure in the measuring chamber and/or the differential pressure between two measuring chambers or pressure-measuring ducts in a rear area of each measuring chamber. The static pressure, the dynamic pressure or the speed of the current can also be calculated.
