Installation requirements

Installation requirements:
In general, the requirements on homogeneous flow conditions and concentrations are met when sampling takes place
in a straight pipe section with an inlet section of at least five hydraulic diameters (5 x DN) and an outlet section of three
hydraulic diameters (3 x DN). In addition, the pipe section must have a constant shape and a constant cross-section.
Inlet zone:
Outlet zone:
For the measuring sections made by BEKO TECHNOLOGIES or for measuring sections which are manufactured
according to the specifications of BEKO TECHNOLOGIES, we recommend guide values for the minimum flow of
the compressed air in the measuring sections, to ensure representative sampling. You will find these guide
values in a table in the Appendix.
