Abstract Rotameters are frequently used to measure the flow of air to positive supply respirators. Depending on where they are mounted on the air supply system, their reading needs to be corrected. This report presents the evaluation of two rotameters for the purpose of establishing the precision of the readings, validating the flow correction equations to be applied and specifying the methodological framework to be used during field measurements. Results clearly show the need for taking temperature and pressure parameters into account for obtaining the true airflow,
