Measurement data during commissioning
Voltage [V]
Temp. of the conveyed air [°C]:
Current L1 [A]*
Impeller speed [rpm]
Current L2 [A]:
Volume flow [m³/h]:
Current L3 [A]:
Differential pressure [Pa]*:
*For single-phase fans, enter in line "Current L1 [A]"
*Δ-pressure between suction and discharge side of the fan
If a volume flow measurement is not possible, the value can be calculated using the following formula:
X
=
Duct cross-section [m²]
Flow velocity [m/s]
Volume flow
[m³/h]:
Grid measurement according to VDI 2044
