  • Page 13: Basics - Flow Measurement

    4 Basics – flow measurement PIOX S72* 4.1 Measurement principle Basics – flow measurement 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. Measurement principle The flow velocity of the fluid is measured using the transit time difference correlation principle.
  • Page 14 4 Basics – flow measurement 4.1 Measurement principle PIOX S72* 4.1.2 Measurement of the flow velocity The signals are emitted and received by two transducers alternatively in and against the flow direction. If the fluid is flowing, the signals propagating in the fluid are displaced with the flow. Caused by this displacement, the sound path of the signal is reduced in flow direction and increased in the opposite direction.
