4.2 Mounting instructions
SITRANS LVL200S has a defined thread starting point. This
means that every 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.
Keep in mind that this welded socket is not suitable for coated
instrument versions.
Screw SITRANS LVL200S completely into the welded socket.
The later position can be determined already before welding.
Mark the appropriate position of the welded socket. Before
welding, unscrew SITRANS LVL200S and remove the rubber
ring from the welded socket. The welded socket has a marking
(notch). Weld the socket with the notch facing upward, or in
case of pipelines, aligned with the direction of flow.

Marking
In case of horizontal mounting in adhesive and viscous
products, the surfaces of the tuning fork should be vertical in
order to reduce buildup on the tuning fork. On the screwed
version you will find a marking on the hexagon. With this, you
can check the position of the tuning fork when screwing it in.
When the hexagon touches the seal, the thread can still be
turned by approx. half a turn. This is sufficient to reach the
recommended installation position.
With flange versions, the fork is directed to the flange holes.
