ABSTRACT:
Apparatus for measuring flow rate and flow direction of a fluid comprises an elongated stem coaxially disposed and supported within an elongated housing, a small diameter spherical probe connected to an end of the stem which projects through an opening in the housing for transmitting to the stem forces exerted on the probe by the flowing fluid, and a sensor for detecting the forces transmitted to the stem and for producing electrical signals representative of a measurement of the flowing fluid. The apparatus may detect forces exerted on the probe in one, two or three orthogonal directions, thereby providing output signals corresponding to the components of a vector representation of the fluid flow.
