    3 General principles FLUXUS F502TE 3.1 Measurement principle General principles In the ultrasonic flow measurement, the flow velocity of the fluid in a pipe is determined. Further physical quantities are derived from the flow velocity and from additional physical quantities, if necessary.
  • Page 12 3 General principles 3.1 Measurement principle FLUXUS F502TE 3.1.2 Measurement of the flow velocity The signals are emitted and received by 2 transducers alternatively in and against the flow direction. If the fluid is flowing, the signals propagating in the fluid are displaced with the flow.
