1 Installation
1.1 Mechanical installation
Use only the recommended sleeves or adapters. When installed with foreign adapters, no
guarantee can be given for proper functioning or leak-tightness.
Do not use Teflon or paper gaskets.
When installing in pipes, it is advisable to align the bore at the sensor in the direction of flow. This
will ensure good exchange of the medium and good cleanability. The display unit is then
positioned at right angles to the pipe. It is not possible to turn the display relative to the channel
bore!
Carefully introduce the measuring head straight into the sleeve. Hold the correctly aligned
measuring head firmly and screw down the union nut with a tightening torque between 20 and 50
Nm.
Correction inputs as a factor of the diameter are not necessary when installing in pipes.
1.2 Process connection
The hygienic ½” process sleeve is easy to weld in into tanks or pipes. The kind of assembly allows
installation in conformity with standards of hygiene (to EHEDG, FDA). The G1/2” and G1”
connections can be mounted in any counter thread acc. to ISO 228.
Various hygienic adapter sleeves (refer to chapter “Accessories”) are available for fitting to other
process connections. For more information refer to data sheet “Accessories”.
