Abstract
This invention provides an expendable velocimeter probe. High frequency transmitting and receiving transducers are mounted opposite to one another in axial alignment on the probe body and on a frame in front of the body. The mounting includes means for accurately adjusting the distance between the transducers in order to provide low cost, but highly reliable, means for calibrating the velocimeter during large scale manufacture of the instruments.
