Graftel has
upgraded its liquid flow calibration capabilities
to
500 Gallons Per Minute. This allows for more flexibility for our
customers to offer a “one-stop” for all of your liquid flow
calibration needs.
Graftel
maintains four primary liquid flow calibration systems utilizing
water as our flow medium. All of our gravimetric water
setups are designed in accordance
with the standard ASME/ANSI MFC-9M-1988, Measurement of Liquid Flow in
Closed Conduits by Weighing Method.
Our newest high-flow
liquid system uses a high-accuracy Coriolis meter to give a best
measurement capability of up to 0.1% of reading up to 500 GPM.

Graftel
maintains five NIST traceable primary gas flow calibration
systems, all of which achieve uncertainties in the 0.2% reading range.
Each system can utilize air, nitrogen, helium and other custom
non-explosive mixtures. These five systems cover overlapping ranges so
that they may be checked against one another. In addition, each system
contains dual primary standards.
The dual
primary standards chosen for each system are different types so that
they cannot contain the same systematic errors. This multiple-standards
approach provides great assurance of the accuracy of the absolute flow
measurement. Flow rates up to 100 scfm at pressures up to 1000 psi may
be achieved. This allows for precise calibration of sonic nozzles,
venturies and orifices.

Graftel maintains
four NIST traceable
primary liquid-flow
calibration systems utilizing water as a medium. These gravimetric water
systems are designed in accordance with the standard ASME/ANSI
MFC-9M-1988, Measurement of Liquid Flow in Closed Conduits by Weighing
Method. These three systems cover overlapping ranges so that they may be
checked against each other. Flow rates up to 500 gpm may be achieved. This allows for the precise calibration
of standard liquid flow meters as well as high pressure venturies, orifices,
and other critical devices.
