2 "This side up" label indicates which side is up
3 Slope the device in accordance with the hygiene guidelines. Slope: approx. 2 ° or 35 mm/m (0.42 in/feet)
4 Transmitter
5 Line on the underside indicates the lowest point of the eccentric process connection.
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.

Zero point adjustment
All measuring devices are calibrated in accordance with state-of-the-art technology. Calibration
takes place under reference conditions→  42. Therefore, a zero point adjustment in the field is
generally not required.
Experience shows that zero point adjustment is advisable only in special cases:
• To achieve maximum measuring accuracy even with low flow rates.
• Under extreme process or operating conditions (e.g. very high process temperatures or very high-
viscosity fluids).
