Omega Engineering Inc.OMEGA® rotameters offer precision variability of air, water and gases, with up to ±2% of full-scale accuracy and 0.25% of full-scale repeatability. These units include an easy-to-read millimeter scale and are supplied with correlation charts for air and water. Correlation data for nitrogen, oxygen, hydrogen, helium, argon and carbon dioxide are also available. The scale is fused on the metering tube in 1-mm (~3/64-in.) increments, which enable a user to read the flow rate with the highest accuracy.
