Installation
26
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 →  258.
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.
