4.2 Mounting instructions
SITRANS LVL200E has a defined thread starting point. This means
that every SITRANS LVL200E is in the same fork position after being
screwed in. Remove therefore the supplied seal from the thread of
SITRANS LVL200E. 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 LVL200E 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 LVL200E 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 (DN 32 up to
DN 50), 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.
When used in adhesive and viscous products, the tuning fork should
protrude into the vessel to avoid buildup. For that reason, sockets for
flanges and mounting bosses should be avoided when mounting
horizontally.
