New FCI ST50 Air/Gas Flowmeter Goes Wireless With IR Link For PDA Communication

Ideal For Municipal & Industrial Wastewater Aeration Control Systems

Wastewater engineers looking for a more convenient, time-saving and lower cost way to communicate with flowmeters will find the new ST50 Flowmeter from Fluid Components International (FCI) not only provides best-in-class measurement and value for line sizes from 2 to 24 inches (51 to 610mm), but it also is now available with an exclusive wireless communication option.

Utilizing a wireless IR technology built-in to the ST50 flowmeter and a standard, low cost PDA, field technicians can obtain measurements, make setting changes and read trouble-shooting codes without ever having to open the instrument. This industry unique feature is ideal in applications for flow meters that are installed in hard-to-reach locations or where opening the instrument is inconvenient or labor intensive.

The wireless IR link eliminates the need for expensive proprietary programmers, which simplifies maintenance and reduces the overall cost of use. FCI’s wireless IR sensing capability is included in all ST50 air/gas flowmeters with a digital display readout. To complete the system, FCI also supplies the easy-to-use, user interface software for downloading into any Palm-OS based PDA.

Now wastewater engineers no longer have to trade-off between accuracy, installation, maintenance, convenience and economy. The ST50 Flowmeter features a precision, highly reliable no-moving-parts design, and with prices beginning at $995.00--it meets the challenge when compared to orifice plates, differential pressure, vortex shedding and other thermal instruments. It is ideal for use in municipal and industrial wastewater aeration control systems, industrial and commercial blower and dryer input/out air flow controls, industrial manufacturing burner and furnace air flow control, HVAC duct/damper control, and aeration flow control in lakes, ponds or aquaculture.

The new ST50 is an insertion-type flowmeter designed with a fully temperature-compensated thermal flow sensing element constructed with precision, lithography etched platinum RTDs embedded in FCI’s patented equal-mass miniature diameter thermowells. Combining microelectronics with FCI’s precise calibration, the ST50 achieves superior accuracy, fast response and virtually maintenance-free operation with negligible pressure drop.

Whenever performance, long-life and total installed costs are all important process considerations, the ST50 offers the best flow instrument value in its class. Operating over a wide range, the ST50 measures 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 +2% of reading, +0.5% of full scale, with repeatability of +0.5% of reading. The versatile ST50 is field configurable for flow range in standard mass flow or volumetric engineering units. In addition to the wireless IR I/O, it features dual analog outputs, 4-20 mA and 0-10 Vdc, which are field assignable as flow rate or temperature and a RS232C I/O port. A 0-1kHz pulse output for totalizing flow is also available as an option. All configurations are easily user set in the field with any standard laptop to the RS232C port and/or via the wireless IR link/PDA.

Designed for long-life in wastewater and other outdoor and field installation conditions, the ST50’s sensing element is constructed of stainless steel with Hast-C tips, and its electronics are housed in an all-aluminum, epoxy-coated enclosure that is NEMA 4X (IP66) rated. It withstands operational pressures up to 500 psig [34 bar (g)] and operates in media temperatures up to 250 degrees F (121 degrees C). The process connection is 1/2-inch MNPT or 3/4-inch MNPT with stainless steel or Teflon ferrule. It is available in three field adjustable U-length probes, 6”, 12” and 18” (152mm, 305mm, and 457mm) to accommodate pipe sizes 2-12” (51 to 305mm) and a variety of mechanical installation requirements. Instrument powering options include both DC (12-36V) and AC (85-265V). The ST50 comes with a 1-year standard warranty.

Fluid Components International is a global company committed to meeting the needs of its customers through innovative solutions to the most challenging requirements for sensing, measuring and controlling flow and level of air, gases and liquids.
