Checking the primary volumetric flow
The supplied primary volumetric flow can be simply checked by
checking the static pressure with a Pa meter and the measuring
tube available from us as accessory.
The pressure transducer is in the area of the hydraulic connec-
tions. After removing the sealing plug, a connection to a Pa me-
ter can be established by means of a hose 8 mm in diameter.
After the measurement is complete, the pressure transducer
must be closed again.
The values read on the meter and the following formula can be
used to to determine the volumetric flow:
V [l/s] = Primary air flow
Ps [Pa] = Static pressure
The K value is taken from the following table:
