It is also advisable to mount the sensor and transmitter separately.

Adapters
Suitable adapters to 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 reducers and expanders.
The nomogram only applies to liquids with a viscosity similar to that of 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.
