FLR Flow Transmitter

Installation & Programming Instructions

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-Figure 3. Electrical 4-Pin Connection tors or data loggers that do not have external sensor

excitation available.

Schematic 1: 4-20 mA connection using target power supply

Schematic 2: 0-5 Vdc or 0-10 Vdc connection using target power supply

Schematic 3: 4-20 mA connection using external power supply

Schematic 4: 0-5 Vdc or 0-10 Vdc connection using external power supply

CAUTION

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.
