EN ISO 5167-1 specifies the straight inlet and outlet distances that must be complied with when installing fittings in pipelines
in order to achieve calm flow conditions. The most important layouts that could lead to turbulence in the flow are shown
below, together with the associated minimum inlet and outlet distances. These ensure calm, problem-free measurement
conditions at the measurement point. 25 x DN 5 x DN
