With its highly intelligent, no-moving-parts design, the ST50 Flow Meter Series from Fluid Components International is now available with a high-precision +1 percent 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 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). The new ST50 high-accuracy flow meter comes with three process connections options: 1/2-inch MNPT or 3/4-inch MNPT with a stainless steel or Teflon ferrule. It is available in three field adjustable U-length probes, 6, 12 and 18 inches (152, 305, and 457mm) to accommodate pipe sizes 2 to 124 inches (51 to 610mm). Instrument powering options include both DC (18-36V) and AC (85-265V). The ST50 comes with a 1-year standard warranty.

The ST50 Series is available with built-in wireless IR communication technology via a standard Palm or other PDA. Obtaining measurements, setting changes and reading trouble-shooting codes can be done without ever having to open the instrument. This handy feature is ideal for use with flow meters that are installed in hard-to-reach locations or where opening the instrument is inconvenient or labor intensive, reveals the company’s press release.
