An optional on-board display is available to view flow rate, total flow,
elapsed time, process gas temperature and alarms. The display is also
used in conjunction with the Configuration Panel for field configuration
of flowmeter settings such as 4 to 20mA scaling, pulse output frequency
scaling, pipe area, zero flow cutoff, flow filtering or damping, display
configurations, diagnostics and alarm limits.
