Analog input settings

The Rosemount 3410 Series 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 System Wiring Diagram
in .
C.6

Analog output settings

The Rosemount 3410 Series Ultrasonic Flow Meter provides two 4-20 mA analog output
signals that are software configurable for either sink or source current. Refer to the System
Wiring Diagram in .
Full HART
which meets the specifications of the HART Communications Foundation can be connected
to a Rosemount 3410 Series Ultrasonic Flow Meter.
C.7

Digital Input

The Rosemount 3410 Series Ultrasonic Flow Meter provides one digital input that can be
used as a general purpose input. The digital input must be configured via the MeterLink
