5.1.2 "Flange" version
The guide tube is firmly welded to the flange, so the insertion length cannot be changed.
Secure the flange and the flange sealing with the flange screws and nuts. The screws, nuts
and seals are the responsibility of the operator and should be chosen dependent upon the
measuring medium. The fixing equipment and sealings must fulfil the requirements of the
EN 1092-1, EN 1514 and EN 1515 standards.
Should the float be unable to pass through the mounting hole, see mounting instructions,
chapter 5.1.1 ""Screw-in body" version".
5.1.3 "Mounting on bypass" version
The level transmitter is mounted on the outside of the bypass tube with suitable mounting
material (non-magnetic) (see following figure).
To ensure a reliable measurement, the guide tube must be mounted free of
tension, without external deformations.
▶
The distance between guide tube and bypass tube must be as slow as possible.
▶
Only floats approved by us can be used.
