5.5.1 DAMPING CONTROL
The FUH1010PVX provides two different data output filter types, Time Average and SmartSlew. Time
Average (recommended) integrates the instantaneous flow rate over a selectable time period. Use the
Time Average function when stability in flow reading is essential. A value entered (in seconds) sets the
time it takes the meter to respond to a rate change. The default is 10 seconds. Enter any amount of time
up to 60 seconds maximum.
SmartSlew performs data scatter damping during steady flow periods while maintaining the ability to
respond to changing flow rates. SmartSlew values range from [1 to 9]. Pick a higher number to slow
meter response to a rate change.
To select Time Average (default):
To access the Damping Control option list press
To move the cursor down to [Time Average] press
To enable Time Average entry press
Use PC numeric keys or Magnetic Wand to enter the new Time Average setting.
To register the new value press
To edit the default SmartSlew setting:
To access the SmartSlew option list press three times.
Scroll the numeric list to the desired choice by pressing
To register the new value press
5.5.2 DEADBAND CONTROL
Use Deadband Control to instruct the 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 computa-
tion) 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 the default setting (0.000):
To enable numeric entry press
Use numeric keys or Magnetic Wand to enter the desired rate (using selected flow rate units).
