Analog input settings
The Rosemount 3410 Series Gas Ultrasonic Flow Meter has the capability to sample analog
temperature (Analog Input 1) and pressure (Analog Input 2) with 4-20 mA signals. These
analog input signals are configured to sink. The two independent analog input circuits are
configured for conventional 4-20 mA service. Also, 24 Vdc isolated power supply connection
is provided for an external power source. Refer to the Field wiring diagram DMC-005324 in

Analog output settings
The Rosemount 3410 Series Ultrasonic Gas Flow Meter provides 4-20 mA analog output
signals that are software configurable for either sink or source current (see
