• Ensure sufficient clear space (min� 120 mm) for installation and removal of the
sensor�
6.2 Installation conditions
To meet the specified measurement accuracy, the defined inlet and outlet pipe
lengths must be adhered to:
• Inlet pipe length: 15 x pipe diameter�
• Outlet pipe length: 5 x pipe diameter�
In case of disturbances on the inflow side additional calming sections (B) are
recommended�
