Brooks Instrument 2530A4A67SVVT Flowmeter

Brooks Instrument 2530A4A67SVVT Flowmeter is a Brooks 2530-series variable-area flowmeter (rotameter) designed to measure clean, dry air in laboratory and instrumentation settings. It specifies a flow range of 0.5 to 5 standard cubic feet per minute (SCFM) for air, with a Viton-sealed inlet valve that provides chemical resistance and reliable sealing in typical workflows. The device offers a direct visual readout from a calibrated flow tube, enabling quick verification of flow at standard conditions (70°F, 1 atm) and easy adjustment as needed. As part of Brooks’ 2500-series family of flowmeters, this model is commonly used on instrument air lines, calibration rigs, and bench-top test setups where low-to-moderate air flow needs to be monitored with a simple, non-powered instrument. Readings are intended to be interpreted against standard-condition references, making it straightforward to compare against other VA flowmeters in the Brooks portfolio.
