Installation
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
40 x DN 5 x DN
flow are shown below, together with the associated minimum inlet and outlet distances. These ensure calm, problem-
free measurement conditions at the measurement point.
