    3.2 Startup, installation The devices are intended for installation in a higher-level system. The intervals for cleaning the operating resources (dust deposits) are specified depending on the degree of IP protection. It is extremely important to ensure that only devices with suitable ignition protection for the zones/categories are installed! It is essential that the installation regulations applicable at the national level, e.g.

    3.4 Repair, maintenance (for applications in Ex areas) Definition of terms as defined in IEC 60079-17: Repair and maintenance: A combination of all activities carried out to maintain an item or restore the object to a state in which it is able to meet the requirements of the relevant specification and ensure the execution of its required functions.

  • Page 8: Instrument Inspection

    4. Instrument Inspection Instruments are inspected before shipping and sent out in perfect condition. Should damage to a device be visible, we recommend a thorough inspection of the delivery packaging. In case of damage, please inform your parcel service / forwarding agent immediately, since they are responsible for damages during transit.

  • Page 9: Operating Principle

    6. Operating Principle This device is an oscillating beam device and works without any movable parts. An orifice plate in the base creates flow resistance, which forces a partial flow to be directed into the oscillator. The gas in the oscillator begins to oscillate. The frequency of oscillation is proportional to the flow of volume.

  • Page 10: Mechanical Connection

    7. Mechanical Connection The measuring sensor should be installed in a horizontal position with the oscillator facing upwards. A slight inclination in the direction of flow is permitted. The arrow on the flange housing must point in the direction of flow. The recommended minimum inlet path is 10 times the diameter of the pipe and the maximum outflow zone 5 times the diameter of the pipe.

    10. Startup During startup, ensure that the shut-off valves upstream and downstream of the device are opened slowly. Avoid increasing the flow velocity to prevent the discharge rate from damaging the sensor. The output frequency of the DOG-... with the electronic options A/B/C/D/E/F/R is proportional to the measuring range.
