FCI Small Line Process Flow Meter Delivers Big Advantages

With the ST98L In-Line Flow Meter, Fluid Components International (FCI) combines precision thermal dispersion mass flow sensing and advanced electronics with exacting fluid calibration and a choice of rugged, industrial enclosures.

The ST98L In-Line Flow Meter comes in two different flow element styles that are application-specific. The –F style element is designed for applications in dry, clean air/gases with fluid temperatures up to 350ºF [177ºC]. The –F design incorporates FCI’s unique equal mass sensor in smaller diameter thermowells.

The –S style flow element is suitable for demanding applications involving dirty or erosive fluids, high moisture content gas or a pulsating flow. The –S element features more robust, thicker wall thermowells and an unshrouded equal mass sensor element that provides a noise-filtered response, extended erosion resistance and easier cleaning.

The advanced ST98L In-Line Mass Flow Meter from FCI delivers precision gas flow rate, totalized flow and temperature measurement. It features high accuracy to ±1% of reading, 0.5% of full scale. Exceptionally consistent, the ST98L offers repeatability to ±0.5% of reading and is temperature-compensated for accurate measurement under variable environments.

The ST98L Flow Meter operates over a flow range from 0.0062 to 1850 SCFM (0.01 to 3,140 Nm3/h). It features a turndown ratio that is factory preset from 10:1 up to 100:1 within the calibrated flow range and operates at pressures up to 250 psig [17 bar (g)].

The ST98L’s thermal mass sensing element is comprised of two all-welded 316L stainless steel thermowells that protect two matched platinum precision resistance temperature detectors (RTDs). The ST98L’s transmitter can be specified as integral with the sensor or remote mounted up to 1000 feet [350m] away. Enclosures are available in multiple configurations, with ratings for hazardous environments that include NEMA Type 4X (IP66), Division 1 Groups B, C, D, E, F, G.
