Figure 39: Bad data (rejection)
The flow rate is again outside the original ±10% Hysteresis window, but the data exists for a time period greater than the
Bad Data Rejection window. In this instance, the meter interprets the data as a new valid flow rate and moves the Hysteresis
window to correspond with the new established flow rate.
