Eleven calibrated NIST-traceable ASME Nozzles of various sizes (i.e. 0.5", 1", 2", 5") can be added up to select ranges for EFA ring calibration at pressures of 1 to 5 inches of Water. In most cases, an entire EFA rig can be calibrated by this single array (from 0.5 to 40 Sq. Inch effective area). Each of these ASME nozzles has been measured multiple times from a NIST traceable sonic nozzle flow rig. These can also be used in place of orifice plates.

CCDI manufactures external sonic nozzles (ranging from .015" to .999") for use in the calibration of airflow stands. We can manufacture smaller or larger sizes to accomodate specific customer needs. We can manufacture smaller or larger sizes upon request.

CCDI manufactures ASME Nozzles (ISA1932 ASME Long Radius) for calibration of EFA Test Equipment. We have sizes available from 0.1 Sq. Inch to 50 Sq. Inch.

CCDI manufactures orifice plates for our airflow stands. Each plate is individually measured to specifications and certified by our highly skilled technicians and specialists.
