    PIOX S70x 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 PIOX S70x 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 PIOX S70x 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 PIOX S70x 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.

    PIOX S70x 5 Selection of the Measuring Point Selection of the Measuring Point Attention! Observe the Safety Instructions for the Use in Explosive Atmosphere (see document SIFLUXUS). The correct selection of the measuring point is crucial for achieving reliable measurement results and a high measurement accuracy.
  • Page 21 5 Selection of the Measuring Point PIOX S70x Tab. 5.1: Recommended transducer position Horizontal pipe Select a measuring point where the transducers can be mounted on the side of the pipe, allowing the sound waves to propagate in the pipe horizontally. Thus, solid at the bottom or gas bubbles at the top of the pipe will not influence the propagation of the signal.
