(2 regs)
Rev_LowFlowCutoff Low Flow cutoff
reverse
For reverse 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).

Low_Flowcut_-
Threshold
Low Flow cutoff
Threshold
Hysteresis preventing frequent on/off
switching of low flow cut-off (in %).
