Calibration

Though all units are calibrated at the factory, all units must be checked for calibration and

recalibrated as required, before their use by customers.

Note: Units must be properly purged before calibration or calibration verif

ication.

Incomplete purging of air can result in inaccurate calibration or errors in calibration

verification testing.

Calibration is accomplished by first pumping the product into

correctly sized prover can to

determine the accuracy of the unit. The size of the prover can is established by Weights and

Measures (W&M), depending on the flow rate of the unit.
