500
GPM 17025 Accredited NIST traceable liquid flow calibrations now available 
Graftel's Labs are open to your
business to perform ISO-17025 accredited NIST traceable liquid flow calibrations up to
500
GPM.
Our newest
high-flow liquid system uses a high-accuracy Coriolis meter in
conjunction with a time-mass weighing system to give reading of up to 0.1% of reading
accuracy at flow rates up to 500 GPM.
Our
current ranges for our ISO-17025 accredited and
NIST certified 500 GPM flow-calibration systems:
-
500
Gallons Per Minute
-
30,000
Gallons per hour
-
1900
Liters per minute
-
113,500
Liters per hour
Graftel Maintains four NIST traceable primary liquid
flow calibration systems utilizing
water* as the calibration medium. Three systems use a static gravimetric method. The fourth is
supplemented by a high-accuracy Coriolis
meter. These four systems cover overlapping
ranges so that they may be checked against each other. Below are the descriptions
of the four primary standards.
