May 24, 2018 — Fluid Components International (FCI) announced an enhanced version of their ST50 Mass Flow Meter Series in order to provide precision measurement of air and increase system efficiency.

The installation of ST50 Series Flow Meters in the process control loops of industrial air blower and dryer systems provides hot air flow rate monitoring.  The use of mass flow meters ensures rate of flow measurement and totalized flow measurement for zone control and overall system operational efficiency.

Relying on FCI’s thermal dispersion mass flow sensing technology, the ST50 Flow meters provide direct mass flow measurement. With the ST50 meter, there is no need for the temperature sensors, flow computers or the other devices required with orifice plates, Venturis, Vortex shedding and other flow meters.  The ST50’s design also provides built-in temperature compensation for measurement over a temperature range with almost no pressure-drop.

The ST50 Flow Meter measures air, compressed air or nitrogen from 0.75 to 400 SFPS (0.23 to 122 MPS) in line sizes from 2 to 24 inches (51 to 610 mm).  Flow meter accuracy is up to +1% of reading, +0.5% of full scale, with repeatability of +0.5% of reading.   The meter operates at temperatures from up to 0 to 250°F (-18 to 121°C). Turndown ratio is up to 100: 1

The flow range of the ST50 Series can be field-configured in either standard mass flow or volumetric engineering units.  In features dual analog outputs: two 4-20 mA outputs, which are field assignable to flow rate or temperature and an RS232C I/O port.  A 0-500 Hz pulse output for totalized flow is also available as an option.  All configurations are user set in the field with any standard laptop to the RS232C port and/or via the wireless IR link/PDA.

The ST50 meter’s stainless steel sensing element with Hastelloy-C tips is designed for endurance in heavy duty plant, outdoor and field installation conditions. Its electronics are housed in an all-aluminum, epoxy-coated enclosure that is NEMA 4X (IP66) rated. The entire ST50 instrument features FM/CSA agency approvals for Class 1, Div 2, Groups A, B, C and D; ATEX, GOST-R, CPA, BelGIM (Belrus), CE Marketing, CRN and PED. 

There are two process connections options available for the ST50 meter: 1/2-inch MNPT or 3/4-inch MNPT with a stainless steel or Teflon ferrule.  It is available in three field adjustable U-length probes: 1-6 inches (25-152mm), 1-12 inches (25-305 mm) and 1-18 inches (25-457mm) for pipe sizes 2 to 24 inches (51 to 610mm). Instrument powering options include both DC (18-36Vdc) and AC (85-265Vac).
