Keep in mind that this welded socket is not suitable for coated

instrument versions.

Screw LEVEL SWITCH 8111 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

LEVEL SWITCH 8111 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), a ligned with the direction of ﬂow.

1 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.

If LEVEL SWITCH 8111 is mounted in the ﬁlling stream, unwanted

false measurement signals can be generated. For this reason, mount

LEVEL SWITCH 8111 at a position in the vessel where no

disturbances, e.g. from ﬁlling openings, agitators, etc., can occur.

To minimise ﬂow resistance caused by the tuning fork, LEVEL

SWITCH 8111 should be mounted in such a way that the surfaces of

the blades are parallel to the product movement.
