Important:
Valves should always be mounted on the downstream side of the flow sensor!

9.5 Pipe System :
1.The flow sensor must be mounted in a location which is free from interfering elements like
valves, Ts, bends, pumps, etc. to ensure a laminar flow without turbulence upstream of the flow
sensor. For that reason the flow sensor must be mounted in a straight pipe at a distance from
interfering elements of minimum 10 x DN upstream and minimum 5 x DN downstream.
The minimum length to keep the angle below 7° can be checked by means of the formula below:
L= (D - d) / (2 x tan
a
) where "D" is the large diameter and "d" the small diameter of the reducer.
Example: If a flow sensor in dimension DN 65 is mounted downstream of a 80 mm pipe,the
reducer must then have a length of minimum 108.80 mm in order to keep the inner angle
below 7°.
3. Flange connections must be assembled concentrically on both the upstream and the
downstream side. Due to improper connection assuring accuracy of flow meter will be affected.
Note:- Gaskets and grounding rings must also be mounted concentrically!
