    • energized state. Incorrect handling or improper use can lead to malfunctions in your application. • Flowcont UN can be used by the Pressure Equipment Directive (PED) of group 2 only for „non- • hazardous liquids.“ Applications The Flowcont UN flow meter is particularly suited for measuring highly dynamic processes in pipelines.

    Commissioning Installation notes An arrow on the measuring channel of the Flowcont UN indicates the flow measurement direction. The measuring device must be installed such that the flow passes through the measuring tube in the direction of the arrow. TOP -> Outlet Bottom ->...

  • Page 6: Mounting

    If the device cannot be mounted vertically, the pipe in which the measuring device is located should always be full. Preventing the formation of gas bubbles in the Flowcont UN measuring channel will aid optimal measurements.
  • Page 7 Application with hot fluids In applications where the Flowcont UN is subject to high heat (t < 60 °C), we recommend mounting the measuring device and electronic housing beneath the measurement area. This allows the heat to radiate upwards and reduces its effects on the device electronics.

  • Page 8: Electrical Connection

    Electrical connection The Flowcont UN is connected via a ready-made cable socket with M12x1 plug, with 5 pins or 8 pins. Plug in the cable socket without power onto the sensor and screw it tight. Connect the cable in accordance with its function. After application of the supply voltage, the sensor carries out a self-test –...

  • Page 14 Units The Flowcont UN is able to show actual flow or the volume in different unities. Following unities can be selected: ml/s + l , Gal/min +Gal , l/min + l , l/min + m³.
  • Page 15 Creeping flow The creeping suppression serves the purpose of excluding flows from the measurement that can evolve through convection in a narrow frame around zero, even with a closed valve. At the factory, the creeping suppression is set at a reasonable standard value in relation to the cross-section of the flow meter.
  • Page 16 Setting area: off, pulse output, empty pipe, lower limit, upper limit, negative flow Media The Flowcont Un dispose of a medium matrix with up to 8 interpolation values. Different medias can be managed in the sub menu “Media”. Matrix values can be saved and if needed be loaded for different medias.
