Universal Flow Monitors” FlowStream OFM mass flowmeters are designed for blanketing gas, purge gas, shielding gas, leak detection, and other applications in industrial, medical, and laboratory settings. The meters allow users to select multiple gases in the field via a pushbutton interface and program for the measurement of air, argon, carbon dioxide, helium, hydrogen, methane, nitrogen, or oxygen. The span of the unit’s transmitted signal can also be changed. The meters can read full-scale flowrates as low as .5 (five-tenths) SCM up to 1,000 SLPM. They can accommodate operating pressures as high as 125 PSI. NIST-traceable accuracies are +/- 1-2 percent.
