ST80 Series Mass Flow Meters
Product Overview
The ST80 is a high performance, thermal dispersion technology air/gas flow meter, combining reliable and feature-rich electronics with the industry’s most extensive selection of flow sensors. This includes FCI’s new “wet gas” flow element, which provides a truly superior solution for industrial processes and plant applications.
The ST80 further combines these features with a robust, rugged transmitter enclosure and industry’s broadest selection of process connections to provide longest service life and ease-of-installation in your installation’s pipe or duct.

Temperature Measurement Range: Up to 850°F [454°C] commensurate with element; see Operating Temperature in Flow Element specification
Media: all gases that are compatible with the flow element materials
Accuracy:
- Flow: ± 1.0% reading, ± 0.5% full scale
- Temperature: ±2 °F [± 1.1°C] (display only, flow rate must be greater than 5 AFPS [1,5 m/sec])
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])
Response Time (Flow): 1 sec. to 63% of final value (1 step change) typical with -FP or -FPC type flow element operating in AST™ mode
Turndown Ratio: Normally factory set and field adjustable from 2:1 to 100:1 within calibrated flow range.
Temperature Compensation:
- Standard: ± 30°F [± 16°C]
- Optional: ± 100°F [± 55°C]
Calibration: Performed on flow stands using equipment traceable to NIST and ISO/IEC 17025
