Abstract
Method for measuring the direction and force of gaseous or 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 chamber openings are positioned in a plane, and the arrangement of the measuring chamber openings relative to each other is fixed. Furthermore a probe for carrying out this method is disclosed.
