Featuring an all-new advanced electronics design, FCI’s thermal air/gas flow meter line now includes HART Version 7 digital bus communication and more. The new Models ST51A, ST75A and ST75AV Thermal Mass Flow Meters from Fluid Components International (FCI) provide users with an economical yet rugged solution to measuring air or gases in demanding industrial process and plant applications. They combine all-new, surface-mount, lead-free, RoHS-compliant electronics with highly accurate, repeatable, all-welded, equal-mass flow sensors.

In addition to HART bus communications, standard ST51A, ST75A and ST75AV outputs are dual 4-20 mA that meet NAMUR NE43 and feature a 500 Hz pulse. The electronics are housed in a rugged, IP67-rated, dual-cable port transmitter enclosure available in aluminum or a stainless steel version. The transmitter can be mounted directly to the flow sensor or remotely mounted up to 100 feet (30 meters) away.

The highly reliable ST51A, ST75A and ST75AV Flow Meters already have obtained the CE mark, and Div.1/Zone 1 Ex agency approvals of FM, FMc, ATEX and IECEx.  Additionally, they have also been independently verified to meet International Electrotechnical Commission's (IEC) standard IEC 61508 for Safety Integrity Level (SIL-1) rating.
