- this table specifies the complete measuring range of the
standard controller (volumetric flow range).
- If the customer absolutely wants a calibration curve different
from 12 m/s, it must be specified!
- When the air volume drops below the V
min
shown in the
chart, the correct functioning of the volumetric flow controller
is no longer guaranteed!
- If only one air volume is specified in the order (as V
max
value),
the volumetric flow controller will be delivered as variable vol-
umetric flow controller. The V
min
value will be set to the value
specified in the catalogue.
- If only one air volume is specified in the order (as V
min
or
V
konstant
value or without value specification), then the volu-
metric flow controller will be delivered as a constant volumet-
ric flow controller. The volume specified in the order is set to
the V
min
value, and the V
max
value is set to 100%.
- The air volumes can be changed using setting devices specif-
ic for the controller make, depending on the calibration curve
set ex works.
- For the parameter setting of the control components (all con-
trollers), an air density of 1.2 kg/m³ has been taken into ac-
count.
- Belimo compact controllers are height-compensated. They
are calibrated ex works to the system height in question of the
specified installation site.
- If no system height is given in the order, the controllers will
be calibrated to the altitude of the delivery address.
- If the customer does not specify whether the "Parallel" or
"Master/Slave" operating mode is desired, the controller is set
for the parallel operation (Master/Slave mode only upon cus-
tomer request).
- for alternative controller types, a V-min from 2 m/s can be set
(pneumatic controllers from 3 m/s)
