Fluid Components ST75 ATEX- and IECEx-approved flowmeter

The Fluid Components ST75 flowmeter is now ATEX and IECEx approved for safety in hazardous and potentially explosive plant environments.

Designed for line sizes of 6-51 mm, the flowmeter provides three outputs: mass flow rate, totalised flow and media temperature. It is suitable for applications in the chemical, electric power, food/beverage, advanced materials, pharmaceuticals and semiconductor industries.

The flowmeter includes media temperature compensation to ensure performance in rugged environments and features accuracy to ±2% of reading with ±0.5% repeatability. Its flow element has no moving parts and employs platinum RTD sensors embedded in equal mass thermowells calibrated to laboratory standards for a range of gases including: natural gas, methane, nitrogen, CO₂, argon, all inert gases and compressed air.

The flowmeter is suitable for low- and high-flow operations. It operates over a wide flow range, from 0.01 to 950 NCMH, depending on line size.

The flowmeter is remote mountable and the remote mount transmitter, which includes a full digital display, can be mounted up to 15 m from its thermal-mass flow sensor in the process piping and connected via two 0.50″ FNPT cables. It provides an accurate, fast response and low-maintenance solution to small line size gas and airflow applications in hard-to-reach or hazardous locations.

The instrument includes a rugged sensing element constructed with all-welded 316 stainless steel and Hastelloy-C tips. It is enclosed in a rugged, all-metal, dust- and water-resistant NEMA Type 4X (IP66)-rated package designed for hazardous area installations.
