If the flow is below the cut-off the flow indication on the display will be
zero. (This function can prevent the flow meter from reading flow after
a pump is shut down but there is still liquid movement in the pipe, which
would result in a flow total error.)
Generally, 0.03ft/s is recommended to enter as the low flow cut off
point. The low flow cutoff value has no relation to the
results once the velocity increases over the low flow cutoff value.
