FT3 Functional Diagram
An on-board 2 line x 16 character backlit LCD display shows ow rate, total ow, elapsed time, process
gas temperature, and alarms. The display is also used in conjunction with the Conguration Panel for
eld conguration of ow meter settings such as 4-20mA scaling, pulse output scaling, pipe area, zero
ow cuto, ow ltering or damping, display congurations, diagnostics, and alarm limits.
