Method for Measuring the Velocity of a Fluid Flow by Means of Electroacoustic Feedback
A new method for measuring the velocity of a fluid is described. It is based on the following principle: an ultrasonic transmitter and an ultrasonic receiver, both immersed in the fluid, are connected respectively to the output and the input of an amplifier which oscillates at a frequency
depending on the velocity of the fluid.
