Functions
7.9 Operation Adjust Menu Settings
Setting SmartSlew:
1. From the [Dual Path Flow] menu scroll to the [Operation Adjust] menu and press <Right
2. At the [Damping Control] menu press the <Right Arrow> and move the cursor down to
3. To access SmartSlew option list press <Right Arrow>.
4. Scroll the numeric list to the desired choice by pressing <Up/Down Arrow>.
5. To register the new value press <ENTER>.
Deadband Control
Use the Deadband Control to instruct the flow meter to report zero flow if the flow rate falls
below a specified level (usually a very low rate). It will prevent the possibility of data scatter
(a natural result of digital computation) from causing false Totalizer accumulation during long
non-flowing periods. Inspect the actual data scatter during zero flow conditions to find the
proper Deadband setting for your application.
To edit Deadband default setting (0.000):
1. From the [Dual Path Flow] menu scroll to the [Operation Adjust] menu and press <Right
2. Scroll to the [Deadband Control] menu
3. Press <Right Arrow>to enable numeric entry.
4. Use the numeric keys to type in the desired rate (using selected flow rate units).
5. To register the new value press <ENTER>.
Memory/Fault Set
Certain situations will interrupt data production (e.g., an empty pipe or excessive aeration).
Use Memory/Fault Set to select the flow meter response to such an interruption. The Fault
setting (default) will zero the flow rate output and declare an alarm on a flow display screen,
Datalogger report and an assigned relay output.
For some applications, occasional temporary Fault conditions may be a normal part of the
process and would not require an alarm response. The flow meter offers a Memory operating
mode to support such an application. Memory Mode suspends the flow meter Fault response
by preventing the flow outputs from dropping to zero for the interval specified in the Memory
Delay menu cell. During the Memory duration, the flow meter will maintain the last valid flow
reading measured before the onset of the fault condition. The default Memory Delay is 60
seconds. You may select any duration from 3 to 604,800 seconds (one week).
Selecting Memory Mode
1. From the [Dual Path Flow] menu scroll to the [Operation Adjust] menu and press <Right
2. Scroll to the [Memory/Fault Set] and press <Right Arrow> to access option list.
