Installation in partially filled pipes
For partially filled pipes or pipes with downward flow and free outlet the flowmeter should be
located in a U-tube.
Installation in large pipes
The flowmeter can be installed between two reducers (for example DIN 28545). At α ≤ 8° the
following pressure drop curves apply. The curves are applicable to water.
Example:
A flow of 3 m/s (v) in a sensor with a diameter reduction from DN 100 to DN 80 (d

= 0.8) gives
a pressure drop of 2.9 mbar.
