Mechanical flow meters ProSense FG1 series mechanical variable area ow meters provide a visual indication of ow rate for water or petroleum-based uids. These meters oer Âą5% full-scale accuracy and a repeatability of Âą1% — important for cyclical applications requiring consistent readings. Two adjustable ow limit pointers are available to provide preset indication of high, low or normal ow rates. The ow meters are constructed of high-impact polysulfone plastic (body, piston, cone) with brass ďŹ ttings (1â „2 and 3â „4 NPT models). FG1 series ow meters are available with 1â „2, 3â „4, or 1-in. NPT process connections and have easy-to-read ow scales in both gallons per minute (gpm) and liters per minute (lpm). Measurement ranges are from 0.25 - 2.5 gpm (1 to 10 lpm) to 4 - 28 gpm (20 to 100 lpm).
Oil-free scroll compressors The W-series of oil-free scroll rotary air compressors generates Class 0 oil-free air quality and oers quiet operation. Scroll compressors meet a broad spectrum of oil-free needs for commercial applications that require contamination-free air, low maintenance, and a smaller footprint. The W-series scroll compressors use an orbital wheel singlestage technology. Two interlacing spiral scrolls pump, compress, and pressurize the air. One scroll remains in a ďŹ xed position, while the other scroll orbits around it without rotating. The motion traps the air in the pockets between the two scrolls and pushes the air towards the center. As the air moves closer to the center, the pockets shrink, and the air compresses. This unique design creates air completely free of oil — there is no oil in the compressor, air, or condensate at all. The scroll compressors have a simple tip seal design with no metal-to-metal contact eliminating metal friction and the need for lubrication while maintaining sealing performance and saving energy.
