I am not aware of any specified requirement for shot flow verification. Users specify both peening intensity and coverage. It is up to the shot peener to achieve both requirements. Coverage rates would obviously be affected by the shot flow rate. There is, however, an indirect effect of shot flow rate on peening intensity. High flow rates will generate lower peening intensities than low flow rates - other parameters being kept constant.
It is in the peener's best interests to ensure that flow regulation equipment e.g. Magnaflow, is properly maintained and calibrated.
