How to Use the Set Empty Command
Use [Set Empty] to enter a number that represents the signal strength level consistent with an empty
pipe. [Set Empty] uses non-linear scaling. There is no direct correlation between the number you enter

pipe. If you set it too high, it could trigger the empty pipe alarm, suspending flow measurement, even
though the liquid is flowing.
To enter an Empty Pipe Alarm Threshold:
To access the [Empty Pipe Set] option list press the <Right Arrow>.
To move the cursor to [Set Empty] press the <Up Arrow>.
Press <ENTER>. The current empty threshold number appears in the prompt.
