Expected Measurement Uncertainty
, when correct installation parameter is applied
± % or l/s depending, which is the greatest of the percentage or the absolute value for the
specific product size.
Dim. 100 = ±5 % or ±1,00 l/s
Dim. 125 = ±5 % or ±1,25 l/s
Dim. 160 = ±5 % or ±2,5 l/s
Dim. 200 = ±5 % or ±4,0 l/s
Dim. 250 = ±5 % or ±6,5 l/s
Dim. 315 = ±10 % or ±10 l/s
NOTE
: The measurement uncertainty is defined in laboratory conditions and may be greater in
practical installations, where non-optimal installation situations or multiple consequent disturbances
may exist.
Fig.3. Minimum safety distances
If the straight duct between the damper and disturbance is less than five times the duct diameter
distance, then the installation factor needs to be added to the airflow controller during
commissioning.
NOTE:
The installation factors can be found in the
Wiring and controller connections
The wiring must be carried out by professional technicians following local regulations. For the power
supply, a safety-isolating transformer must be used.
