Handling

Welded socket

The process ﬁtting must be sealed if there is gauge or low

pressure in the vessel. Before use, check if the seal material is

resistant against the measured product and the process

temperature.

The max. permissible pressure is speciﬁed in chapter

"Technical data" or on the type label of the sensor.

The vibrating level switch is a measuring instrument and must

be treated accordingly. Bending the vibrating element will

destroy the instrument.

Warning:

The housing must not be used to screw the instrument in!

Applying tightening force can damage internal parts of the

housing.

Use the hexagon above the thread for screwing in.

4.2 Mounting instructions

For welded socket with O-ring in front and welding marking.

SITRANS LVL100 has a deﬁned thread outlet. This means that

every SITRANS LVL100 is in the same position after being

screwed in. Remove therefore the supplied ﬂat seal from the

thread of SITRANS LVL100. This ﬂat seal is not required when

using a welded socket with front-ﬂush seal.

Before welding, unscrew SITRANS LVL100 and remove the

rubber ring from the welded socket.

The welded socket has a marking (notch). For horizontal

mounting, weld the socket with the notch facing upward or

downward; in pipelines aligned with the direction of ﬂow.
