    Prior to setup you have to replace these protective caps with ap- proved cable glands or close the openings with suitable blind plugs. Note: Process conditions For safety reasons, the instrument must only be operated within the permissible process conditions.

  • Page 16: Mounting Instructions

    Mounting instructions Installation position Mount VEGAFLEX 86 in such a way that the distance to vessel instal- lations or to the vessel wall is at least 300 mm (12 in). In non-metallic vessels, the distance to the vessel wall should be at least 500 mm (19.7 in).
  • Page 17 Higher sockets or sockets with a bigger diameter can generally be used. They can, however, increase the upper dead zone. Check if this is relevant for your measurement. In such cases, always carry out a false signal suppression after mounting. You can find further information under "Setup procedure". VEGAFLEX 86 • Two-wire 4 … 20 mA/HART...
  • Page 18 Unfavourable mounting 2 Socket flush - optimum mounting Welding work Before beginning the welding work, remove the electronics module from the sensor. By doing this, you avoid damage to the electronics through inductive coupling. Inflowing medium Do not mount the instruments in or above the filling stream. Make sure that you detect the product surface, not the inflowing product. VEGAFLEX 86 • Two-wire 4 … 20 mA/HART...
  • Page 19 You can thus measure the complete range of the medium in the bypass tube (h). When designing the bypass tube, keep the dead zone of the probe in mind and select the length of the bypass tube above the upper lateral filling opening accordingly. VEGAFLEX 86 • Two-wire 4 … 20 mA/HART...
  • Page 20 If durability is no problem, we recommend the use of uncoated metal standpipes. When the VEGAFLEX 86 is used in bypass tubes, contact with the tube wall must be avoided. We recommend for this purpose a cable probe with centering weight.
