    • The device must be operated by persons authorized and trained by the facility's owner-operator. Strict compliance with the instructions in these Operating Instructions is mandatory. • Endress+Hauser is willing to assist in clarifying the chemical resistance properties of parts wetted by special fluids, including fluids used for cleaning. However, small changes in temperature, concentration or the degree of contamination in the process can result in changes of the chemical resistance properties.

  • Page 10: Return

    • Always enclose a fully completed "Declaration of Contamination" form with the device. Only then can Endress+Hauser transport, examine and repair a returned device. • Enclose special handling instructions if necessary, for example a safety data sheet as per European Directive 91/155/EEC.

  • Page 16: Installation Conditions

    3 Installation Proline Prowirl 73 Installation conditions Note the following points: • The measuring device requires a fully developed flow profile as a prerequisite for correct volume flow measurement. The inlet and outlet runs must be taken into account (see Page 19).

  • Page 17: Orientation

    Proline Prowirl 73 3 Installation 3.2.2 Orientation The device can be installed basically in any orientation. Please consider the following, however (Fig. 6): • In the case of liquids, there should be upward flow in vertical pipes to avoid partial pipe filling (see orientation A).

  • Page 18: Heat Insulation

    3 Installation Proline Prowirl 73 3.2.3 Heat insulation Some fluids require suitable measures to avoid heat transfer at the sensor to ensure optimum temperature measurement and mass calculation. A wide range of materials can be used to provide the required insulation.

  • Page 19: Inlet And Outlet Run

    Proline Prowirl 73 3 Installation 3.2.4 Inlet and outlet run As a minimum, the inlet and outlet runs shown below must be observed to achieve the specified accuracy of the device. The longest inlet run shown must be observed if two or more flow disturbances are present.
