Abstract
A nozzle for a gap measuring system includes a short outlet passageway defined by a smooth, cylindrical wall terminating in an outlet orifice and having an entrance orifice surrounded by a wall portion that is substantially perpendicular to the outlet passageway. As fluid flows through the nozzle, it encounters the surrounding wall portion at the entrance of the short outlet passageway of the nozzle which constricts the fluid flow upon entry into the short outlet passageway of the nozzle. As a result of the nozzle geometry, the fluid exits the nozzle outlet with a higher velocity, lower pressure and decreased turbulence. The incorporation of such a nozzle into a gap measuring system can produce an increase in the reliability and accuracy of distance determinations nearly ten times that which was previously attainable with prior nozzle inserts.
