About Field Rotameters
These small and lightweight, single-ball rotameters represent a new and durable design of portable air flowmeters. SKC Field Rotameters are crafted of see-through acrylic with tapered hose connectors attached to solid brass fittings. A removable section of Tygon^® tubing with a Luer taper adapter is included. A float ball is clearly visible behind decaled graduations on the rectangular face. The easy-to-read scales are ideal for performing routine verifications of air flow easily in the field with reproducible results.

The ball-type flowmeters and rotameters built into most air sampling pumps are primarily intended to serve as flow indicators and are, therefore, of low accuracy. These flowmeters as well as rotameters must be calibrated against a primary standard such as a film flowmeter or electronic calibrator (Defender) to verify accuracy.

When using a rotameter at a different temperature and pressure than when it was calibrated, the following formula can be used to calibrate the new flow rate: Q2 = Equivalent flow rate in L/min or ml/min at calibration location Q1 = Measured flow rate in L/min or ml/min P1 = Pressure in mm Hg at sampling location P2 = Pressure in mm Hg at calibration location T1 = Temperature in degrees Kelvin (degrees Celsius + 273) at sampling location T2 = Temperature in degrees Kelvin (degrees Celsius + 273) at calibration location
