    The measuring equipment has to be checked for proper condition and operational safety before each use. If troubles or damages have occurred during installation or operation of the measuring equipment, please inform FLEXIM. It is not allowed to make unauthorized modifications or alterations to the measuring equipment.

  • Page 9: Not Intended Use

    • With the exceptions stated in chapter 10, the measuring equipment is maintenance-free. Any components and spare parts may only be replaced by FLEXIM. The operator shall carry out periodic checks for changes or damages that can present a danger. For further information, contact FLEXIM.

  • Page 11: General Principles

    3 General principles FLUXUS WD 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 WD 3.1.2 Measurement of the flow velocity in the TransitTime mode 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.
  • Page 13 3 General principles FLUXUS WD 3.1 Measurement principle Fig. 3.3: Transit time difference ∆t ∆t 1 – signal in the flow direction 2 – signal against the flow direction 3.1.3 Measurement of the flow velocity in the NoiseTrek mode If the proportion of gas or solids in the fluid is high, the damping of the ultrasonic signal can be so high that the complete propagation of the fluid and therefore a measurement in TransitTime mode is not possible anymore.

    3 General principles 3.2 Measurement arrangements FLUXUS WD 3.1.4 Measurement of the flow velocity in the HybridTrek mode The HybridTrek mode combines the TransitTime and the NoiseTrek mode. During a measurement in the HybridTrek mode, the transmitter automatically toggles between the TransitTime and the NoiseTrek mode depending on the gaseous or solid content.
