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 and any standard amplitude unit. If you set the number too low, the meter
may not detect a true empty pipe. If you set it too high, it could trigger the empty pipe alarm
even though the liquid is flowing.
To enter an Empty Pipe Alarm Threshold:
To access the [Empty Pipe Set] option list press
To move the cursor to [Set Empty] press
Press . The current empty threshold number appears in a pop-up window.
Use PC numeric keys or Magnetic Wand to enter a new [Set Empty] number.
To store the [Set Empty] number press
2.5 THE OPERATION ADJUST MENU
This menu becomes available after picking a meter type and measurement channel.
We recommend that you use it after the transducers are installed and operating to “fine-
tune” the meter’s output characteristics.
Each application presents different data display and output requirements due to unique pipe
and liquid conditions. Use the Operation Adjust menu to match meter operation to the site.
You can also select the meter response to a continuous fault condition.
