  • Page 12 You can find further information in the operating instructions manual "Bypass tube VEGAPASS 81". If you mount the VEGAFLEX 81 in a bypass tube or standpipe, you Spacer have to avoid contact to the bypass tube by using a spacer at the probe end.

  • Page 13: Mounting

    Instructions for installation Installation position Mount VEGAFLEX 81 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 14 If this is not possible, use short sockets with small diameter. Higher sockets or sockets with a bigger diameter can generally be used. They simply increase the upper blocking distance. Check if this is relevant for your measurement. VEGAFLEX 81 • Modbus and Levelmaster protocol...
  • Page 15 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 81 • Modbus and Levelmaster protocol...
  • Page 16 If durability is no problem, then we recommend the use of metal standpipes. When the VEGAFLEX 81 is used in standpipes or bypass tubes, contact with the tube wall must be avoided. We recommend for this purpose a cable probe with centering weight.
  • Page 17 Rod extensions In case of difficult installation conditions, the probe can be also mounted laterally. For this purpose, adapt the rod with rod extensions or bow-shaped segments. VEGAFLEX 81 • Modbus and Levelmaster protocol...
