U N I V E R S A L FLOW RANGE F L O W 1-2100 SCFH (50 SCCM-1000 SLPM) MAX PRESSURE ® OFS (Single Gas) Series 100 PSIG (6.8 Bar) M O N I T O R S FlowStream® UNIVERSAL Flow Monitors ® FlowStream® Mass Flowmeters for Gases TYPICAL APPLICATIONS • Blanketing • Sparging/Purging Gases General Description • Burner Management • Assist Gases Laminar Flow Element differential pressure owmeters are good for clean, dry, non-corrosive, non-condensing gasses. Corrected for temperature and pressure, it has a mass ow output. The EMI immunity and fast response (5 ms available) make the meters suitable for robotics’ applications (painting or welding). A variety of outputs are available (4-20 mA, 0-5 V, and pulse). NIST traceable and CSA units are Type 4 weatherproof. The accuracy is a uniform 1% of full scale subject to limitations described in the Specications section. • Leak Tests • Injectable Gases • Shielding Gas • Gas Consumption • Gas Blending • Gas Chromatography Features Units with a display can indicate ow rate or total as well as gas temperature and pressure. Meter types • Output options: current, voltage, frequency, and scaled pulse • Programmable set points • Open collector outputs • Intrinsically safe for hazardous location use - CSA and CE Calibration is done on air with empirically derived conversion factors. Oxygen cleaning optional. Sizes range from 1/4 to 3/4 inch NPT. Anodized aluminum is the standard material for the meter body and 316 Stainless Steel is available for use where external corrosion is a factor. Selectable options for installed units • Response time (5 or 50 ms) • Open collector set point ow rates • Range of electrical output • Visual readout of ow rate or total, pressure and temperature 1
