Calibration/Verification of Rotameters

[dennis.hadlock@srs.gov]

All,

I would like to know how often you calibrate/verify the rotameters associated with air sampling equipment at your facility and to what accuracy.  This would be for both installed and mobile air sampling systems/equipment.  We are currently calibrating our rotameters annually with a +/- 15% accuracy and would like to try and justify a longer calibration period.

Please respond to me directly unless you feel your response would be appreciated by the entire list.

Thanks for you help,
