Schematics
The transmitter can be wired in various configurations
to allow interface with many different types of data col-
lection and control instrumentation.
Schematics 1 & 2 represent typical wiring for a target
powered by either AC power or DC supply.
Schematics 3 & 4 will be utilized when the flow trans-
mitter is operated with loop-powered process indica-
tors or data loggers that do not have external sensor
excitation available.

Figure 4. Terminology

The flow transmitter is designed to operate only one
of its three outputs at a time (i.e.,0–5 Vdc or 0–10
Vdc or 4–20 mA). Connecting multiple outputs
simultaneously will result in inaccurate output signal
levels.
