    FLUXUS F70x 2 Handling Handling First Inspection The measuring instrument has already been tested thoroughly at the 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 F70x General Principles For the ultrasonic measurement of the flow rate, the flow velocity of the medium flowing in a pipe is determined. Further physical quantities (e.g., volumetric flow rate, mass flow rate, heat flow rate) are derived from the flow velocity and from additional physical quantities, if necessary.
  • Page 12 FLUXUS F70x 3 General Principles Sound speed c Speed of the propagating sound. The sound speed depends on the mechanical properties of the medium or the pipe ma- terial. In pipe materials and other solid materials, a distinction is made between the longitudinal and transversal sound speed.

  • Page 14 FLUXUS F70x 3 General Principles 3.2.3 Measurement of the Flow Velocity in the NoiseTrek Mode When media 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 medium. A measurement in the TransitTime mode is no lon- ger possible.
