# If the PF2A721 is in window comparator mode, and the hysteresis is 3 digits what flow rate is this e

Last Updated: September 16, 2018The full scale of the PF2A721 is 200L/min, and 1 digit is equivalent to 2L/min, therefore 3 digits is equivalent to 6L/min.

The resolution of the instantaneous flow rate display is 2L/min.
