Flow meters shall be verified using equipment calibrated to the National Institute of Standards and Technology (N.I.S.T) standards. This equipment shall be calibrated at least annually or if accuracy of the equipment is questioned. B&B Calibration recommends that flow meters meet these same standards as a company requirement. If you already have a calibration procedure in place we can meet your requirements.
In an effort to verify current gas flow readings on welding machines, B&B Calibration uses a calibrated flow meter calibrated to NIST Standards for verification.
Flow meters that are outside of 10% of readings will be recommended to be rebuilt or replaced.
Upon verification of a flow meter, a calibration sticker is affixed to the meter and a calibration certificate is mailed or hand delivered to the company representative along with the written procedure for verification,
