Centering If you mount the SITRANS LG270 in a bypass tube or standpipe, you have to avoid contact to the bypass tube by using a spacer at the probe end. You can find additional information in the operating instructions manual "Centering".
  • Page 13: Mounting

    Make sure before mounting that all parts of the instrument exposed to conditions the process are suitable for the existing process conditions. These are mainly: • Active measuring component • Process fitting • Process seal Process conditions in particular are: PBD-51041064 SITRANS LG270 - Operating Instructions...
  • Page 14: Mounting Instructions

    Mounting instructions Installation position Mount SITRANS LG270 in such a way that the distance to vessel installations 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 15 In such cases, always carry out a false signal suppression after mounting. You can find further information under "Setup procedure". ≤ 150 mm ( 5.91") DN40 ...

  • Page 16 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. Fig. 8: Mounting of the sensor with inflowing medium Measuring range The reference plane for the measuring range of the sensors is the sealing surface of the thread or flange.

  • Page 17 If durability is no problem, we recommend the use of uncoated metal standpipes. When the SITRANS LG270 is used in bypass tubes, contact with the tube wall must be avoided. We recommend for this purpose a cable probe with centering weight.
  • Page 18 For standpipes, select the probe length such that the upper blocking distance (dead band) of the probe is above the upper ventilation hole. This allows you to measure the total level range of the medium in the SITRANS LG270 - Operating Instructions PBD-51041064...
  • Page 19 If durability is no problem, we recommend the use of uncoated metal standpipes. When the SITRANS LG270 is used in standpipes, contact with the tube wall must be avoided. We recommend for this purpose a cable probe with centering weight.
  • Page 20 Instructions for the measurement: • The 100 % point with standpipes should be below the upper ventilation hole. • The 0 % point in standpipes should be above the gravity or center- ing weight. SITRANS LG270 - Operating Instructions PBD-51041064...
  • Page 21 Make sure that the probe cable is not completely taut. Avoid tensile loads on the cable. Avoid undefined vessel connections, i.e. the connection must be either grounded reliably or isolated reliably. Any undefined change of this condition can lead to measurement errors. If there is a danger of the rod probe touching the vessel wall, fasten the probe at the bottom end. PBD-51041064 SITRANS LG270 - Operating Instructions...
  • Page 22 Keep in mind that measurement is only possible up to the tensioning component. For this reason, order the cable probe 270 mm longer. L = L1 + 270 mm (10.63 in) SITRANS LG270 - Operating Instructions PBD-51041064...
  • Page 23 Rod extension In case of difficult installation conditions, for example in a socket, the probe can be suitably adapted with a rod extension. To compensate for the resulting changes in signal runtime, let the instrument determine the probe length automatically. You can find further information in the supplementary instructions of the rod and cable components. PBD-51041064 SITRANS LG270 - Operating Instructions...
