Thermal mass flowmeter for CO₂

Food and beverage plants that require carbon dioxide or produce CO₂ as a by-product will find the advanced ST75 Flow Meter from Fluid Components International (FCI) delivers precise direct mass flow measurement of gases in an easy-to-install, insertion-style instrument that requires almost no maintenance over a long life.

The ST75 Flow Meter is suitable for the measurement of CO₂ in a variety of industrial applications, including in the bottling of beverages that include soda drinks, beer and sparkling wine.

The flowmeter is a rugged and reliable instrument designed for demanding process industry plant environments. With an extensive set of standard features, the ST75 is designed for line sizes from 6 to 51mm. The ST75 provides three outputs: the mass flow rate, totalised flow and media temperature.

With accuracy to ±1% of reading and ±0.5% repeatability, the ST75’s design includes media temperature compensation to ensure performance under variable process and plant temperature conditions. Its precision flow element has a no-moving-parts design that employs platinum RTD sensors embedded in equal mass thermowells with microprocessor electronics that can be calibrated to laboratory standards for CO₂ as well as many other gases.

The ST75 Flow Meter operates over a wide flow range, from 0.01 to 950 NCMH depending on line size, which makes it equally well suited to low- and high-flow applications. For variable process conditions, the ST75 is factory preset to a wide turndown range at 10:1 to 100:1.

For CO₂ measurement and monitoring, the ST75 provides an accurate, fast response and low-maintenance solution for carbon dioxide applications. Whether adding flow sensing to improve a process or replacing poorly performing or high-maintenance flowmeters, it is an efficient and economical choice for flow measurement and monitoring in a variety of industries.
