Flow Meter Calibration - Qualifications?

[jartgo]

Wondering if there are any certifications or licensing typically required or issued for flow meter calibration? That is, I have calibrated a few flow meters for clients over the last year and just written them a letter stating what I did. A competitor has suggested to a client that you must be certified to do so. I've not heard of such requirements. In the past, when I hired a meter rep to calibrate a meter they just issued a letter, with no reference to licensing/certifications.

What have you all experienced? I'm in North Carolina. Thanks.

The meter manufacturer has the ability to test and certify meters.

Typically, the local water meter testing firms test the meters according to the AWWA Standard---Water meters--selection, installation, testing, and maintenance By American Water Works Association.

I am not aware of any licensing requirements.

In my opinion this is a big problem in Pennsylvania. I know of no requirement for any license or registration needed in order to “certify’ meter calibration. There is and has been a requirement by PA PUC for calibration of water custody meters, but this only extended to the test equipment. In another life, I required all in house meter techs to maintain a water or wastewater license. I am having two problems today with a magmeter and a Parshall flume that have questionable calibrations. In each case the tech (contract) will happily make the meter read anything I want!
