Abstract
Abstract The invention disclosed is an instrument for sensing, measuring, and indicating the velocity components in, the resultant velocity and direction of flow of, and turbulence occurring within a moving fluid medium. It incorporates a fluid movement responsive spherical sensor tethered by a trio of taught wires containing strain gages, one or more computers (depending on the parameters being calculated), and a readout calibrated in terms of the information desired during given operational circumstances.
