Rotameter calibration is sometimes an overlooked issue by the companies that utilize them. However, OSHA requires that the rotameter be “periodically” calibrated to a primary standard. During its use, a rotameter will accumulate foreign material inside and will eventually lose its sensitivity to measurement. Although a rotameter has limited moving parts, they do perform a measurement for flow accuracy and therefore should be a standard part of your Q/A manual process.

|Rotameter 1 to 4 liters per minute||$20 per rotameter|
