Installation conditions

Inlet section

≥

5 x DN

Outlet section

≥

3 x DN

Note: Straight inlet and outlet sections are not required for accuracy

reasons, but may reduce instable flow indication caused by fluctuating flow

profiles and may increase lifetime because of reduced mechanical wear.

It is recommended to consider the inlet / outlet sections especially for

devices

≥

DN50 / 1".

Protect devices from vibration and high-

frequency oscillation

Use in accordance with IEC 61298-3 in control room or field with medium

vibration level.
