Abstract
A method of determining the velocity of a flowing material, suspended in a liquid and flowing in a conduit, including irradiating the conduit with ultrasonic waves, detecting first Doppler-shifted reflections of the waves from the material, which first reflections have a positive Doppler-shift, and detecting second Doppler shifted reflections of the waves from the material, which second reflections have a negative Doppler-shift. The flow velocity is estimated based on the extent of the positive and negative Doppler-shifts. The first and second reflections may be summed to form a composite signal and the range of Doppler-shifts in the composite signal is used to estimate the flow velocity.
