3.2.5 Foundations, supports
If the nominal diameter is DN ≥ 350, mount the sensor on a foundation of adequate load-
bearing strength.

Caution!
Risk of damage! Do not support the weight of the sensor on the metal casing.
The casing would buckle and damage the internal magnetic coils.

3.2.6 Adapters
Suitable adapters to (E) DIN EN 545 (double-flange reducers) can be used to install the
sensor in larger-diameter pipes. The resultant increase in the rate of flow improves
measuring accuracy with very slow-moving fluids.
The nomogram shown here can be used to calculate the pressure loss caused by cross
section reduction:
!
Note!
The nomogram applies to fluids of viscosity similar to water.
1. Calculate the ratio of the diameters d/D.
2. From the nomogram read off the pressure loss as a function of flow velocity
(downstream from the reduction) and the d/D ratio.
