  • Method and device for measuring volume flows in liquids and gases
    Patent number: 5325726
    Abstract: A method and device for measuring a volume flow of fluids in flow channels using ultrasound, wherein two ultrasonic transducers, each with a different transmitting frequency, are disposed in a flow channel in such a manner that emitted wave trains travel toward one another, with speed vectors of both wave trains having components that are in the flow direction and against the flow direction, and the superimposed signal is evaluated in terms of its position with respect to time.
