Table 1 – Minimum flow rate measuring section
For the exact measurement of the oil content, the sampling manner is of special importance. The sample shall be
taken at a point ensuring the presence of a representative and usable mixture of all compressed air components.
As far as gaseous and vaporous organic substances are concerned, it can be assumed that they are sufficiently
homogenously distributed over the measuring cross-section. At a homogenous distribution, the gases can be
taken at a defined point approximately in the middle of the measuring cross-section.
For the measuring sections made by BEKO TECHNOLOGIES or for measuring sections which are manufactured
according to the specifications of BEKO TECHNOLOGIES, we recommend the following guide values for the
minimum flow of the compressed air in the measuring sections, to ensure representative sampling:
* The minimum flow rate is based on standard m
3
The standard m in accordance with ISO 1217 is based on 1.0 bar abs. and +20°C.
