Accuracy:
Flow:
Gas Specific Calibration: ± 0.75% reading, ± 0.5% full scale
SpectraCal Gas Equivalency: Typically ± 4% reading, ± 0.5% full
scale;
gas conditions specific to application will determine accuracy; utilize
FCI’s online tool, AVAL, to evaluate your application and provide
expected accuracy

than 5 AFPS [1,5 m/sec])
Pressure (STP Models): ± 0.25% full scale pressure range
Temperature Coefficient
With optional temperature compensation; valid from 10% to 100%
of full scale calibration
Flow: Maximum ± 0.015% of reading / °F up to 850 °F
[± 0.03% of reading / °C up to 454 °C]
Repeatability
Flow: ± 0.5% reading
Temperature: ± 1 °F [± 1 °C] (flow rate must be greater than 5 AFPS
[1,5 NMPS])
Turndown Ratio
Normally factory set and field adjustable from 2:1 to 100:1
within calibrated flow range; up to 1000:1 possible with factory
evaluation of application
Temperature Compensation
Standard: ± 30 °F [± 16 °C]
