Fluid Components International ST75 air/gas flow meter

Tuesday, 01 September, 2020 | Supplied by: AMS Instrumentation & Calibration Pty Ltd



The ST75 air/gas flow meter from Fluid Components International measures fuel gas, process gas, inert gas, waste gases and air in small line sizes. With built-in temperature compensation, the flow meter maintains consistent performance in rugged, hot industrial process environments.

Suitable for use in food/beverages, chemical processing, electronics manufacturing, power generation, pharmaceuticals, metals and materials industries, the flow meter operates over a wide flow range, from 0.01 to 559 SCFM (0.01 to 950 NCMH) depending on line size. For variable process conditions, the ST75 is factory preset to a wide turndown range at 10:1 to 100:1.

It features accuracy to ±2% of reading with ±0.5% repeatability over varying process temperatures in line sizes from 6 to 51 mm. With a Vortab flow conditioner added as a spool piece, the models ST75V or ST75AV are suitable for installations with limited straight-run and/or for operating in transitional flow ranges with accuracy of ±1% reading, ±0.5% full scale.

The meter’s precision flow element has a no-moving parts design that employs platinum RTD sensors embedded in equal mass thermowells with microprocessor electronics calibrated to laboratory standards for a wide range of gases.

It features remote mounting capabilities for hazardous or crowded plant environments. The remote mount transmitter, which includes a full digital display, can be mounted up to 15 m away from its thermal mass flow sensor in the process piping and connected via two 0.50″ FNPT or M conduit connections. ST75’s scalable dual 4–20 mA standard outputs are user assignable to flow rate and/or temperature and a 0–1 kHz pulse output of total flow. The instrument can be ordered for input power with either 18 to 36 VDC or 85 to 265 VAC, with or without a built-in LCD digital display.
