Airflow Ranges (CFM)
1
Minimum and maximum airflow limits are dependent on the specific DDC controller supplied. Contact the control vendor to
obtain the minimum and maximum differential pressure limits (inches W.G.) of the transducer utilized with the DDC controller.
2
Maximum CFM is limited to value shown in General Selection Data.
FlowStar™ Calibration Chart
(For dead-end differential pressure transducers)
NOTE: Maximum and minimum CFM limits are dependent on the type of controls that are utilized. Refer to the table below for
specific values. When DDC controls are furnished by others, the CFM limits are dependent on the specific control vendor that is employed.
After obtaining the differential pressure range from the control vendor, the maximum and minimum CFM limits can be obtained from
the chart above (many controllers are capable of controlling minimum setpoint down to .015" w.g.).
