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.
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.
