Rain Bird PT322 Pulse Transmitter — No Display
Brand: Rain Bird | SKU: PT322
Product Overview
The Rain Bird PT322 converts signals from a compatible flow sensor into a scaled pulse output for supported Maxicom and SiteControl systems. Choose it when you need a compact interface between the sensor and central control, with readings viewed through the connected system rather than a display on the transmitter.
Key Features
- Scales Rain Bird FS Series flow-sensor signals for a supported central-control installation.
- Two diagnostic LEDs indicate input and output activity.
- Computer programming lets the installer match the sensor calibration and pulse output to the receiving system.
- Compact solid-state module with snap-fit electrical connectors.
Common Uses
- Replacing a PT322 in an existing compatible flow-monitoring installation.
- Adding flow-sensor feedback to a supported Maxicom or SiteControl configuration.

Compatibility & Installation Notes
Select the interface from the actual controller and communication architecture. Rain Bird specifies a pulse decoder such as DECPULLR for supported hard-wire two-wire satellite arrangements; other supported systems use different connections. A PT322 is not a universal sensor decoder for every two-wire controller.
Confirm access to the correct programming software, communication cable and a compatible computer before ordering. The legacy programming manual describes older Windows systems and does not establish compatibility with current Windows versions.
With power isolated, follow the supplied terminal markings and applicable system instructions. Select the exact sensor and pipe configuration or verified K-factor and offset, then match pulse scaling and units to the receiving controller. The flow sensor and suitable power source are separate system requirements.
Frequently Asked Questions
Does the PT322 show flow on its own display?
No. The PT322 has diagnostic LEDs but no built-in flow display. Readings are viewed through the supported connected system or programming software.
Is the PT322 a flow sensor?
No. It receives a compatible sensor signal and converts it into a scaled pulse output. The sensor must be selected separately for the pipe and flow conditions.
What power does the PT322 require?
Rain Bird specifies a 12–30 VAC/VDC supply. Confirm the supply and wiring against the transmitter and system instructions before connecting power.
Can I program it with any modern laptop?
Programming requires the appropriate Rain Bird software, communication connection and a compatible operating system. Confirm the computer setup before purchase; the legacy manual does not verify current Windows compatibility.
Why Buy from Big Frog Supply?
The PT322 makes sense for an installation that already calls for Rain Bird’s compact, no-display pulse interface: it accepts a 12–30 VAC/VDC supply and provides separately visible input/output LEDs for troubleshooting. Match its programmable output to the existing sensor and central-control architecture before choosing it over a monitor with a local display.
