    FLUXUS F808, F809 2 Handling Handling First inspection The measuring instrument has already been tested thoroughly at factory. At delivery, proceed to a visual control to make sure that no damage has occurred during transportation. Check that the specifications of the measuring instrument delivered correspond to the specifications given on the pur- chase order.

  • Page 11: General Principles

    3 General principles FLUXUS F808, F809 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.
  • Page 12 FLUXUS F808, F809 3 General principles Sound speed c Speed of the propagating sound. The sound speed depends on the mechanical properties of the fluid or the pipe material. In pipe materials and other solid materials, a distinction is made between the longitudinal and transversal sound speed. For the sound speed of some fluids and materials see annex C.1.

  • Page 14 FLUXUS F808, F809 3 General principles 3.2.3 Measurement of the flow velocity in the NoiseTrek mode When fluids with a high proportion of gas bubbles or solid particles are measured, the attenuation of the ultrasonic signal increases and can inhibit the propagation of the signal in the fluid. A measurement in the TransitTime mode is no longer possible.

  • Page 15: Measurement Arrangements

    3 General principles FLUXUS F808, F809 NoiseTrek parallel beam For small pipes or highly damping fluids, the transit time of measuring signals can be very small due to scattering bodies and bubbles. This leads to a deterioration of the signal quality. The NoiseTrek parallel beam mode works the same way the NoiseTrek mode does, the only difference is that the sending and receiving process do not occur in the same transducer.
  • Page 16 FLUXUS F808, F809 3 General principles Beam The path covered by the ultrasonic signal between the transducers: the transducer emitting the ultrasonic signal and the transducer receiving it. A beam consists of 1 or several sound paths (see Fig. 3.9 or Fig. 3.10). Fig.
