FCI’s Compact Thermal Flow Meter Delivers Precise Gas Measurement for Dosing and Injection Control

SAN MARCOS, Calif. – June 30, 2025 – In markets in which specific gas application and shot are important, such as chemical, biomedical, and oil/gas manufacturing, designers will certainly discover the portable ST75 Collection Air/Gas Circulation Meter from Liquid Elements International (FCI) provides them a dependable service for exact circulation dimension in jampacked devices locations.

FCI’s trustworthy ST75 Circulation Meter uses innovative thermal diffusion picking up innovation, offering exact and regular dimensions also in tough atmospheres. This meter is suitable for procedures needing specific application or shot of several gases: Ammonia, Argon, Co2, Chlorine, Ethane, Fluorine, Nitrogen, Ozone, Refrigerants, Sulfur Dioxide and a lot more.

The ST75 Collection Thermal Air/Gas Circulation Meter appropriates for gases that are generally made use of in a large range of markets. It is extensively trusted for procedures that create innovative products, biomedicines, chemicals, electronic devices, food/beverage, mining/metals, oil/gas manufacturing and refining, plastics, drugs, pulp/paper, water therapy and a lot more.

All gas application and shot procedures have one crucial point alike: The gas circulation price and the totalized circulation of gas need to be determined with high precision and repeatability for set quality assurance and affordable functional performance. The accuracy ST75 Circulation Meter’s solid-state thermal diffusion mass circulation picking up component with platinum RTD’s is housed in equivalent mass thermowells for many years of hassle-free solution.

This meter determines practically any kind of gas or gas combination. It is adjusted to gauge particular gases in FCI’s very own innovative NIST-qualified Calibration Research laboratory. It is offered for requiring applications needing a circulation variety from 0.04 to 559 SCFM (0.07 to 950 NCMH), relying on line dimension, which serves in low-flow applications needing tiny dosages.

The ST75 Circulation Meter, when made use of in variable need cycles because of tiny set or various other continual procedure manufacturing demands, is manufacturing facility predetermined to 100:1 turndowns. It includes extremely reputable precision to ± 1% of checking out with ± 0.5% repeatability in line dimensions from 0.25 to 2 inches (6 to 51 mm). Designers can depend on it for specific circulation control of gases to make sure top quality end-products from either set or continual procedures.
This meter’s circulation component includes a tough, no-moving components style for premium integrity. This special style supplies additional self-confidence where procedure safety and security is a huge worry about various other kinds of meter modern technologies, which depend on movable components that can damage in time in high turndown applications. These occurrences can send out unsafe meter particles collapsing with pipelines sharing unsafe flammable gases.

The Version ST75 Circulation Meters are made with an option of installing setups. They include a complete electronic display screen and are likewise offered with optional transmitter remote installing abilities for unsafe plant atmospheres. The remote transmitter can be totaled 100 feet (30 meters) far from its thermal mass circulation sensing unit in piping or ductwork and linked through 2 0.50-inch FNPT or M avenue links.

For tube solution in a 0.25-inch line, the portable ST75 Circulation Meter’s round transmitter is 3.28 inches (83 mm) broad and stands just 5.7 inches (144,8 mm) over the centerline of the circulation tube. Its fairly tiny impact makes it less complex to include determining factors where close control of the procedure is preferable, such as in gas application and gas shot applications.

In jampacked devices designs that endanger straight pipeline competes exact circulation dimension with various other modern technologies, the Version ST75AV Meter includes an integrated Vortab circulation conditioner. Close-by pumps and shutoffs that influence the precision of various other meter modern technologies are no worry with the ST75 Meter’s integrated Vortab Circulation Conditioners, which develop a normal, smooth circulation account in the pipeline for reputable circulation dimension.

This meter’s totally scalable twin 4-20mA typical results are individual assignable to stream price and/or temperature level and a 0-1kHz pulse outcome of total amount circulation. Two-way HART bus interactions are offered with the Versions ST75A and ST75AV. The tool can be gotten for input power with either 18 to 36 Vdc or 85 to 265 Vac

The ST75 Circulation Meter stands up to procedure temperature levels from 0 to 250 ° F( -18 to 121 ° C). It runs at stress as much as 240 psig [16.5 bar (g)] with a conventional t-fitting (NPT lady) procedure link. With a tube procedure link, the meter stands up to 600 psig [41 bar (g)].

Its electronic devices are housed in a tough, IP67-rated unit with twin avenue ports in either NPT or M20 threading. The designs ST75A and ST75AV consist of HART or Modbus along with NAMUR-compliant 4-20 mA results and SIL conformity score. The full tool brings worldwide Ex-spouse firm authorizations for Department l/Zone 1 installments.

A DwyerOmega brand name, FCI provides specific circulation and degree tool dimension services making use of innovative thermal diffusion modern technologies. With greater than 60 years of experience and the globe’s biggest mounted base of thermal circulation meters, circulation buttons, and degree buttons, FCI is the relied on professional in circulation and degree instrumentation.
