Model 320 Programmable Pulse

OVERVIEW

The Model 320 from Badger Meter is a compact, programmable
transmitter designed to accept relatively fast unscaled raw pulses
from devices like flow sensors, and then output slow-scaled pulses
of programmable width, pulse resolution and units of measure.
In addition to our standard flow sensors, the Model 320 can also
accept a sine wave signal, making it a versatile transmitter for
numerous applications.

With an onboard microcontroller and digital circuitry, the Model
320 is programmed using a Windows® based computer program.
This eliminates the need to set dip switches and produces precise,
accurate and drift-free signals of high resolution.

The compact cast epoxy body measures 1.75 x 2.75 x 1 inches
(44 x 70 x 25 mm) and can easily be mounted to panels, DIN rails
or enclosures. With multiple inputs, ease of use and a variety
of enclosures, the Model 320 is a powerful and competitive
transmitter for many of today’s demanding applications.

Product Data Sheet

Transmitters, Model 320 Programmable Pulse

CALIBRATION

Units can be pre-set at our facility or easily programmed in the field. Field programming requires an A301-20 programming kit (consisting
of a custom cable and software) and a PC running Windows 7, XP or Vista. To program, the Model 320 must be connected to power, and the
A301-20 cable must be connected to an available 9-pin port on the computer. Once the software is loaded and communications with the
transmitter are established, the following parameters are entered on the setup screens:

• Units of measure

• K and Offset values manually entered from values in sensor operator’s manual or automatically entered using the “calculate” button

• Units per output pulse

• Filter setting

• Pulse width

Once the values are set, the “send” command loads the transmitter. A full explanation of all settings is available in the software help file.

WIRING

Per standard wiring practices, the loop power must be off before making any wire connections. The terminal strips have removable plug-in
connectors to make wiring easier. Refer to Figure 4 for terminal connections. An example of typical wiring is shown in Figure 5.

1. Connect power supply positive (+) or AC Load to terminal marked AC
L /DC (+).

2. Connect power supply negative (–) or AC Common to terminal
marked AC C /DC (–).

3. If wiring a 200 sensor, connect the red wire to the
Signal (+) terminal, black wire to Signal (–) terminal, and the shield to
the Shield terminal (Disregard shield for the IR sensors).

If wiring a 4000 sensor, connect the red wire to the Power Out
terminal, clear wire to Signal (+) terminal, black wire to Signal (–)
terminal, and shield wire to the Shield terminal.

If wiring to a sine wave output sensor, consult the factory.

4. Connect Pulse (+) from pulse input device to Pulse Out (+) of the
Model 320. Connect Pulse (–) from pulse input device to Pulse Out (–)
of the Model 320.

5. For maximum EMI protection, connect the ground lug to panel ground.

6. Make sure all connections are tight, then plug the connector into the header.
