    4 Mounting Mounting General instructions • General information For mounting of VEGASOURCE 81 you need a special handling permit. • Mounting may only be carried out by authorized, qualified person- nel who are monitored for radiation exposure according to local laws or the handling permit. Take note of the specifications in the handling permit. Also take the local conditions into account. • Carry out all work within the shortest possible time and at the larg- est possible distance.

  • Page 21: Mounting Instructions

    To do this you have to mount the source container so that the lugs are in a horizontal position. The source holder VEGASOURCE should be mounted as close as possible to the vessel. VEGASOURCE 81 • Source holder...
  • Page 22 In the case of bulk solids, the reaching of a limit level on a large container cross- section can be reliably detected. To do this, select the largest possible beam exit angle and mount the source holder rotated by 90°. VEGASOURCE 81 • Source holder...
  • Page 23 For pipeline diameters 50 … 100 mm (1.97 … 3.94 in), a diagonal radiation path is recommended. The distance of the beam through the medium is thus longer and an improved measuring effect is achieved. For this, the optional lead shielding for the detector is recommended in order to avoid influence from secondary radiation sources. VEGASOURCE 81 • Source holder...
  • Page 24 Vertical pipeline, diameter 50 … 420 mm (1.97 … 16.54 in) For pipeline diameters 50 … 420 mm (1.97 … 16.54 in), a straight radiation path is possible. The radiometric sensor can be mounted either horizontally or vertically. VEGASOURCE 81 • Source holder...
