Holding with Poor Sig
Select "Yes" to hold last good flow signal displayed if
the Flowmeter experiences a poor signal condition.
This function will allow to calculate flow totalizer
data without interruption. Select "NO", instead.
Empty Pipe Setup
This parameter is used to overcome the possible
problems that usually show up when the pipe being
measured is empty. Since signals can be transmitted
through the pipe wall, the flow meter may still read a
flow while measuring an empty pipe. To prevent this
condition from happening, you can specify a value.
When the signal quality falls below this value, the
measurement stops automatically. If the flow meter is
already able to stop measuring when the pipe is empty,
a value in the range of 30 to 40 should also be entered
in this window to ensure no measurement when the
pipe is empty.
