When the sensor is installed in a horizontal line, eccentric clamps can be used to ensure
complete drainability. When the system is pitched in a specific direction and at a specific
slope, gravity can be used to achieve complete drainability. The sensor must be mounted in
the correct position to ensure full drainability in the horizontal position. Markings on the
sensor show the correct mounting position to optimize drainability.

Sanitary compatibility
• When installing in hygienic applications, please refer to the information in the
"Certificates and approvals/hygienic compatibility" section →  255
• In the case of measuring devices with the order code for "Housing", option B
"Stainless, hygienic", to seal the connection compartment cover, screw it closed
finger-tight and then tighten it by another 45° (corresponds to 15 Nm).
Securing with mounting clamp in the case of hygiene connections
It is not necessary to provide additional support for the sensor for operational performance
purposes. If, however, additional support is required for installation purposes, the
following dimensions must be observed.
Use mounting clamp with lining between clamp and measuring instrument.
