Graftel
maintains five NIST traceable primary gas flow calibration systems. Each
system achieves uncertainties in the 0.2% of reading range.
Our
three lowest flow rate gas systems utilize a gravimetric primary
standard. Laminar flow elements are used as secondary working standards.
These secondary standards are periodically verified while in use against
the gravimetric primary standards.
Our
two highest flow rate gas systems utilize sonic nozzles. These systems
are periodically calibrated against a static gravimetric primary
standard.
