4.6.7 Installation in the vicinity of pumps
• For flowmeter sensors that are installed near pumps or other
vibration-causing fixtures, the use of mechanical vibration control
components is mandatory.

4.6.8 Installing the high temperature design
The high temperature design allows for complete thermal insulation
of the sensor. The pipeline and sensor must be insulated after
installing the unit according to the following illustration.

4.6.9 Installation in pipelines with larger nominal
diameter
Determine the resulting pressure loss when using reduction pieces
(1):
1. Calculate the diameter ratio d/D.
2. Determine the flow velocity based on the flow range nomograph
(Fig. 25).
3. Read the pressure drop on the Y-axis in Fig. 25.
