Compressed Air Best Practices - November 2008 - (Page 44) | 11–12/08 Compressed Air Industry STEEL & METALS | RESOURCES FOR ENERGY ENGINEERS PRODUCT PICKS New Thermal Mass Flow Meter Fluid Components International announces the ST50 Flow Meter Series is now available with a highprecision +1 % accuracy configuration for line sizes from 2 to 24 inches (51 to 610mm) and is suitable for applications in air, compressed air, HVAC and process gases, including nitrogen. The new high-accuracy ST50 Flow Meter features FCI’s thermal dispersion mass flow sensing technology, which provides direct flow measurement for higher performance at a lower cost. With the ST50, there is no need for the temperature sensors, flow computers or other devices required with orifice plates, Venturis, Vortex shedding and other meters. The ST50’s unique design also provides built-in temperature compensation for reliable measurement over a wide temperature range with almost no pressure-drop. The versatile ST50 features a wide flow range, measuring air flow from 1 to 125 sfps (0.3 to 38 nmps), nitrogen from 1 to 150 sfps (0.3 to 46 nmps) and compressed air from 4 to 400 sfps (1.2 to 122 nmps). Accuracy is +1% of reading, +0.5% of full scale, with repeatability of +0.5% of reading. It operates at temperatures from +40 to 100° F (4 to 38° C).

Flo-Trol eliminates many of the limitations that currently exist with compressor control systems offered by compressor manufacturers. Some of Flo-Trol’s advantages include: p p Flo-Trol is non-proprietary, using off-the-shelf components Flo-Trol is able to control and monitor all types and manufacturers air compressors and vacuum pumps Flo-Trol eliminates the need to designate a lead compressor or establish a cascading pressure band system p Over the last 15 years and 200 installations, Flo-Trol has evolved into a very powerful and sophisticated control and monitoring system. Our Electro-Pneumatic Control department has applied the expertise and knowledge, gained through experience, to develop a complete family of U.L. Listed controllers under the Flo-Trol name. We are utilizing state-of-the-art hardware and software such as Allen Bradley’s MicroLogix and CompactLogix controllers and Panelview touch screens to provide our customers with all the benefits this new technology has to offer. John Henry Foster is also well versed in the integration of Flo-Trol with Building Management Systems. We have extensive experience with Local Area Network technologies, such as Ethernet.
