100 % of rated volume flow in forward flow
direction.

Fwd_LowFlowCutoff Low Flow cutoff
Forward
For forward flow rates with smaller
magnitude than this cutoff value, totalisers
stop counting and outputs (such as the
frequency output) will be disabled; flow rate
indication will still be available (in m/s).
