Compressed Air Loss Guesstimator for Digital Ultraprobes
Procedure for using the UE SYSTEMS INC. ULTRAPROBE Models
3000/9000/10,000/15,000 to locate and roughly measure air leakage
in compressed air systems.
Use the scanning module to conduct the broad scanning to pinpoint
the air leaks. The scanning module with rubber focusing probe is
used to determine the air losses. The tip of the rubber focusing
probe should be fifteen inches away from the leak location for
determination of the leak rate.
Notice: The values presented in this table are not stated as
factual CFM measurement. This table is provided solely for
convenience and should only be used as a general guideline.
Factors such as turbulence, leak orifice configuration, pressure,
moisture and instrument sensitivity can significantly affect your
results.
For information on measurement of total compressed air system loss
contact your local compressed air vendor or contact UE Service
Partners to have a compressed air specialist provide this service
for you.
