2. Safety Information

Please read and understand all safety instructions before installing or operating the Rain Bird FG100 Flow Sensor. Failure to follow these instructions may result in property damage, injury, or death.

• Electrical Safety: Ensure all power to the irrigation controller and associated components is turned OFF before performing any wiring.
• Water Pressure: Always relieve water pressure from the irrigation system before installing or servicing the flow sensor.
• Proper Installation: Install the sensor according to local plumbing and electrical codes.
• Children and Pets: Keep the product and its components out of reach of children and pets.
• Intended Use: Use this product only for its intended purpose of monitoring water flow in irrigation systems. Do not use for potable water applications unless specifically approved.

3. Package Contents

Verify that all items are present in the package before beginning installation:

• Rain Bird FG100 1-Inch Wired Flow Sensor (Model: XCZPGA100PRF)
• Installation Guide / User Manual (this document)

Note: Additional plumbing fittings, wiring, and irrigation controller are sold separately.

4. Setup and Installation

Proper installation is crucial for accurate flow monitoring. Follow these steps carefully:

1. Plan Location: Select a suitable location in your main irrigation line, typically after the master valve and backflow preventer, but before any zone valves. Ensure there is sufficient straight pipe run (e.g., 10 pipe diameters upstream and 5 pipe diameters downstream) for accurate readings. The sensor is designed for wall mount if needed for support.
2. Turn Off Water and Power: Close the main water supply to the irrigation system and turn off all power to the irrigation controller.
3. Cut Pipe: Carefully cut a section of the 1-inch irrigation pipe to accommodate the flow sensor. Ensure clean cuts.
4. Install Sensor: Thread the Rain Bird FG100 Flow Sensor into the cut pipe section using the NPT threaded unions. Ensure the flow arrow on the sensor body points in the direction of water flow. Use appropriate thread sealant (e.g., PTFE tape or pipe dope) to ensure a watertight seal. Do not overtighten.
5. Wiring: Connect the sensor's wires to your compatible irrigation controller's flow sensor input terminals. Refer to your irrigation controller's manual for specific wiring instructions. Typically, flow sensors use two wires for signal and a third for ground, but consult your controller's documentation. Ensure all connections are secure and waterproof.
6. Restore Water and Power: Slowly open the main water supply, checking for leaks. Once confirmed leak-free, restore power to the irrigation controller.
7. Configure Controller: Access your irrigation controller's settings (via the controller interface or a compatible app on your smartphone/tablet) to enable and calibrate the flow sensor. Follow the controller's instructions for flow sensor setup and calibration.

5. Operating Instructions

Once installed and configured with your irrigation controller, the Rain Bird FG100 Flow Sensor operates automatically to monitor water flow.

• Real-Time Monitoring: The sensor continuously measures the rate of water flowing through your irrigation system. This data is transmitted to your connected irrigation controller.
• Leak Detection: Your irrigation controller, using data from the flow sensor, can detect abnormal flow rates (e.g., flow when all zones are off, or excessively high flow during a zone's operation).
• Alerts and Shutdown: Upon detecting an anomaly, the controller can trigger alerts (e.g., via a smartphone app) and, if configured, automatically shut down the irrigation system to prevent water waste and property damage.
• Water Usage Reporting: Many compatible controllers and apps provide detailed reports on water usage, allowing you to track consumption and identify trends.

Refer to your irrigation controller's user manual for specific instructions on how to view flow data, set up alerts, and manage your system using the flow sensor input.

6. Maintenance

The Rain Bird FG100 Flow Sensor is designed for minimal maintenance. However, periodic checks can ensure optimal performance and longevity.

• Visual Inspection: Periodically inspect the sensor and its connections for any signs of leaks, physical damage, or debris accumulation.
• Cleanliness: If the sensor is exposed to the elements, ensure it remains free of excessive dirt or plant growth that could impede its function or damage wiring.
• Winterization: In regions subject to freezing temperatures, ensure the irrigation system, including the flow sensor, is properly winterized to prevent freeze damage. This typically involves draining water from the system.
• Recalibration: If you suspect inaccurate readings, consult your irrigation controller's manual for instructions on how to recalibrate the flow sensor.
