Air/Gas Flowmeters service flow range from 0.008-839 scfm.
Press Release Summary:
Combining non-clogging, thermal dispersion sensing element with microprocessor-based electronics, Series ST75 measures air or gas flows in line sizes from 0.25-2.0 in. Units provide 3 outputs of mass flow rate, totalized flow, and media temperature with accuracy of ±2% of reading and ±0.5% repeatability. Standard outputs, fully scaleable from 4-20 mA and 0-10 V, are user assignable to flow rate and/or temperature and also include 0-1 kHz pulse output of total flow.
Original Press Release:
New Air/Gas Flowmeter Delivers High-Accuracy, Low-Cost Solution to Small-Line Flow Measurement
Ideal For Fuel & Air Flow Measurement to Boilers, Burners, Chillers, Furnaces, Heat Treating Systems, Turbine & Co-Gen Power Generators, and More
San Marcos, CA-December 16, 2004-Engineers and technicians tasked with improving small line size gas and air flow measurement and control for industrial processes will find the new ST75 Series Flowmeter from Fluid Components International sets a new price-performance standard by offering a simple and more reliable solution at the lowest cost in its class.
Blending high accuracy with extensive features, the ST75 Series Flowmeter measures and monitors air or gas flows in line sizes from 0.25 to 2.0 inches (6 to 51mm) with a single instrument and provides three unique outputs of the mass flow rate, totalized flow and media temperature. Combining a non-clogging, small-size thermal dispersion sensing element with sophisticated microprocessor-based electronics and precision calibration, the ST75 Flowmeter delivers fast, direct mass flow measurement without the need for any other sensors to reduce installation complexity and eliminate maintenance scheduling.
The ST75 Flowmeter is available in nine different line size configurations between 0.25 and 2 inches (6 to 51 mm) in standard T-fittings, either NPT or tube, for quick, easy in-line installation. It services a wide flow range, from 0.008 to 839 SCFM (0.013 to 1425 NCMH) depending on line size, which makes it equally well suited for low flow and high flow applications.
The ST75 provides excellent ±2% of reading accuracy with ±0.5% repeatability and includes media temperature compensation to ensure performance in typical industrial environments. Standard outputs are fully scaleable 4-20mA and 0-10V that are user assignable to flow rate and/or temperature and a 0-1kHz pulse output of total flow. The instrument can be ordered for powering by 24Vdc or 115/230VAC and with or without a built-in LCD digital display.
The ST75 Flowmeter was developed to be the lowest cost, small-line mass flow solution for use in processes flowing natural gas, methane, other fuel gases, combustion air as well as oxygen, nitrogen and all inert gases and compressed air. It is ideal for use in fuel and air feed lines to furnaces, burners, industrial ovens, heat treating systems, boilers, and power co-gen equipment found in a wide variety of manufacturing and process industries. In compressed air distribution lines, where significant energy cost savings can be realized by improving efficiency of compressors, the ST75 accurately measures actual air flow and is sensitive enough at low flows to signal leakage.
Designed with FCI's proven thermal dispersion sensing technology, the ST75's rugged sensing element features 316 stainless steel construction with Hastelloy-C tips. Its no-moving parts design ensures superior service life. There are also no orifices or inlets to clog or foul, which significantly reduces scheduled maintenance and eliminates unplanned shut-downs.
The ST75 is an ideal replacement for differential pressure, orifice plate, turbine and vortex technology meters in rugged or dirty plant environments. The ST75 is enclosed in a rugged, all-metal, dust and water resistant, NEMA Type 4X (IP66) rated package that is designed for hazardous area installation in Groups B, C, D, E, F, G and Eex d IIC environments. Whether adding flow sensing to improve a process or replacing poorly performing or high-maintenance flowmeters, the ST75 provides an accurate, fast response and low-maintenance solution to small line size industrial gas and air flow applications.
