Fluid Components International”s ST50 aeration flowmeter, which supports line sizes from two to 24 inches (51 to 610 mm), is now available with an exclusive wireless communication option. Utilizing built-in wireless IR technology, the ST50 flowmeter and a standard PDA allow field technicians to obtain measurements, make setting changes, and read troubleshooting codes without ever having to open the instrument. The wireless feature is a good fit for applications of flowmeters in hard-to-reach locations where opening the instrument is inconvenient or labor intensive. Wireless IR sensing capability is included in all ST50 aeration flowmeters with a digital display readout. To complete the system, FCI supplies user-interface software for downloading into any Palm OS-based PDA. The meter measures air flow from one to 125 SFPS (0.3 to 38 NMPS), nitrogen from one to 150 SFPS (0.3 to 46 NMPS), and compressed air from four to 400 SFPS (1.2 to 122 NMPS). Accuracy is +/- 2 pecent of reading, +/- 0.5 percent of full scale, with repeatability of +/- 0.5 percent of reading. The meter is field configurable for flow range in standard mass flow or volumetric engineering units. In addition to the wireless IR I/O, the meter features dual analog outputs, four to 20 mA and zero to 10 VDC. Designed for long-life in outdoor and field installation conditions, the meter’s sensing element is constructed of stainless steel with Hasteloy C tips. Its electronics are housed in an all-aluminum, epoxy-coated enclosure that is NEMA 4X (IP66) rated and FM/CSA approved for hazardous location installations. It withstands operational pressures up to 500 PSIG [34 bar (g)] and operates in media temperatures up to 250 F (121 C).
