Dual-Technology Measuring Ensures Field Performance and Application Adaptability Find your gas here? FCl’s ST100A Series is the only thermal dispersion flow meter to deploy both constant power (CP) and constant temperature (CT) thermal dispersion measuring techniques in the same instrument. For many applications the ST100A will be factory set in FCl’s patented AST ™ (Adaptive Sensing Technology) mode. AST ™ is a hybrid that combines both CT and CP techniques in the same circuit. In AST ™ operation the instrument measures in CT mode when in lower flow ranges or startup conditions, and will transparently...

Two Sensor Averaging System Up to Five Unique Calibrations Applications involving line sizes 12 inches [305 mm] or greater can realize improved installation accuracy and repeatability by averaging the flow rates of two elements. Distorted, swirling and non-repeatable flow profiles can result in decreased accuracy of single point meters. In many cases, it is impractical or impossible to provide the required straight-run for a fully developed flow profile in large lines. Models ST102AA and ST112AA overcome these flow profile concerns with a simple, economical “dual-element averaging system.” The transmitter...

Add Pressure Measurement with “STP” Models On-Board Data Logger The “STP” models are the only thermal dispersion gas mass flow meters available featuring pressure measurement to create a triple function solution (flow + temperature + pressure) in a single tap point insertion instrument – an industry first and FCI exclusive feature. A precision strain gauge pressure transducer is built into the STP probe assembly and integrated into the transmitter inputs and outputs. The transducer, connections and wiring assembly are enclosed within a compact, protective aluminum housing and incorporated into the...

FCI’s World Class Calibration Ensures Installed Accuracy ST100A Series In-Situ Calibration Validation Self-Test ST100A Series models are tested and calibrated to rigorous standards so that you get the instrument that does the job specified. To design and produce the highest quality flow instrumentation, FCI operates a world-class flow calibration laboratory with calibrations performed on more than 19 different flow stands, using equipment traceable to NIST (US National Institute of Standards and Technology), and ISO/IEC 17025 (International Standards for test lab quality systems). To achieve the...
