Abstract
A non-invasive method for measuring the velocity of a fluid surface flowing in a predetermined direction in a channel or flume 10 includes the steps of generating a microwave frequency electrical signal adapted to reflect from the fluid surface; spacing the generation of the electrical signal from the fluid surface; directing the signal along a line toward the fluid surface and opposite the predetermined direction and at an angle of between 30.degree. and 40.degree. to the fluid surface; detecting the signal reflected from the fluid surface; and determining from the directed and reflected signal the Doppler frequency shift therebetween as a measure of the velocity of the fluid surface.
