4.1.13 Setting the low cut flowrate
The low cut flowrate is a digital cut-off that can be configured to force the analog or pulse output to 0%
when the flow is below a predetermined value. This parameter is used especially to lock out erroneous
flow signals that may occur below Qmin, where it may be desirable to have the meter drop to zero rather
than provide erroneous readings.
To set the low cut flowrate; move to menu H: Maintenance , then move down to H07: L.C. Flowrate . Using
the numeric keypad input the low flow cut-off flowrate in flow span units. Once this value is stored, any
signal below the low cut flowrate will generate a 0% output.
