Sizing Chart
Example: A MagFlux with an internal diameter of 100 mm can measure
flow rates between approx. 290m
3 /h and 5.6 m 3 /h, and the fluid velocity is
1.5 m/s at a flow rate of approx. 42 m 3 /h.
Size
Pipe System
1. The flow sensor must be mounted in a location which is free from inter-
fering 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 3 x DN upstream and minimum 2 x
DN downstream.

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