  • Page 12 With flange versions, the fork is directed as follows to the flange holes. Fig. 5: Fork position with flange versions Use the recommended cables (see chapter "Connecting to Moisture power supply") and tighten the cable gland. SITRANS LVL200S l RELAY (DPDT)
  • Page 13 (e.g. by cleaning processes) or on cooled or heated vessels. Fig. 6: Measures against moisture penetration Do not hold SITRANS LVL200S on the tuning fork. Particularly Transport with flange or tube versions, the tuning fork can be damaged just by the weight of the instrument.

  • Page 14: Mounting Instructions

    SITRANS LVL200S is in the same fork position after being screwed in. Remove therefore the supplied seal from the thread of SITRANS LVL200S. This seal is not required when using a welded socket with O-ring in front.
  • Page 15 To minimise flow resistance caused by the tuning fork, Flows SITRANS LVL200S should be mounted in such a way that the surfaces of the blades are parallel to the product movement. SITRANS LVL200S l RELAY (DPDT)

  • Page 16: Connecting To Power Supply

    Take note of the general installation regulations. As a rule, connect SITRANS LVL200S to vessel ground (PA), or in case of plastic vessels, to the next ground potential. On the side of the housing there is a ground terminal between the cable entries.
