    3 General Principles FLUXUS WD100, WD200 General Principles For the ultrasonic measurement of the flow rate, the flow velocity of the fluid flowing in a pipe is determined. Further phys- ical quantities (e.g., volumetric flow rate, mass flow rate) are derived from the flow velocity and from additional physical quantities, if necessary.
