Deadband Controls
The meter has two separate and independent deadband controls. One deadband control is
for energy flow rate and the other is for volume flow rate. Follow the instructions below to set
each deadband control as desired.
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.
Note
The units of the numerical entry (e.g. kGal, BTU/HR, etc.) are the same as the Display Units
for each item of energy flow or volume flow.
Note that each deadband setting is independent of the other. For example, if the Volume
flow rate falls below the deadband setting for the volume flow, the Volume flow rate will be
reported as zero. However, if the Energy flow rate remains above the deadband setting for
the energy flow rate, the system will continue to report the measured energy rate (i.e. it will
not be zero.).
