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.
