Inlet and outlet conditions
To achieve accurate flow measurement it is essential to have straight lengths of inlet and outlet
pipes and a certain distance to pumps and valves.
It is also important to centre the flowmeter in relation to pipe flanges and gaskets.
Figure 4-5
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.
