3. Setup
3.1 Battery Installation
The water flow meter requires one CR2032 button cell battery (included). To install or replace the battery:
- Locate the battery compartment cover on the back of the meter.
- Use a coin or the provided key to twist and open the cover.
- Remove any protective plastic tab from the battery if present.
- Insert the CR2032 battery with the positive (+) side facing up.
- Replace the battery compartment cover and twist to secure it. Ensure the rubber ring is properly seated for waterproofing.

3.2 Connecting the Meter
The RAINPOINT Water Flow Meter features 3/4" NH brass inlet and outlet threads for quick and secure connection to standard garden hoses, faucets, and sprinklers. It supports all-direction installation.
- Ensure the threads on your hose or faucet are clean and free of debris.
- For a leak-proof seal, apply the provided sealing tape (PTFE tape) to the threads of your hose or faucet before attaching the meter.
- Screw the meter onto your water source (faucet or hose) by hand until snug. Do not overtighten.
- Connect your watering device (hose, sprinkler, nozzle) to the outlet of the meter.

4. Operating Modes
The RAINPOINT Water Flow Meter features two control buttons: a green button with a circular arrow (Flip/Reset) and a green button labeled 'MENU'.
4.1 Screen Flip (180°)
Press the green button with the circular arrow (Flip/Reset) to rotate the display 180 degrees. This feature allows for easy reading regardless of the meter's orientation during installation.
Figure 6: 180° Flip Reading. This image clearly demonstrates the meter's 180-degree screen flip function, making it easy to read the display from any angle.
4.2 Changing Units (Gallon/Liter)
To switch between Gallons (GAL) and Liters (L), press and hold the 'MENU' button until the unit changes on the display.
Figure 7: GAL / L Switch at Will. This image shows the meter actively measuring water flow and highlights its capability to switch between gallon and liter units for consumption tracking.
4.3 Measurement Modes
Press the 'MENU' button to cycle through the four available measurement modes:
- FLOW RATE: Displays the real-time water flow in Gallons per Minute (GAL/Min) or Liters per Minute (L/Min).
- LAST: Shows the total water consumption from the last watering session. This mode resets after 30 seconds of water stopping.
- TOTAL 1: Accumulates total water consumption. This mode can be manually reset by pressing and holding the Flip/Reset button.
- TOTAL 2: Accumulates total water consumption, independent of Total 1. This mode can also be manually reset by pressing and holding the Flip/Reset button.
Figure 8: Four Measurement Modes. This image illustrates the four distinct measurement modes available on the meter: Total 1 (single water consumption), Total 2 (total water consumption), Flow Rate (real-time water flow), and Last (last water consumption).
Figure 9: Total 1 and Total 2 Modes. This image highlights the meter's ability to track two separate total water consumption values, useful for different measurement periods or applications.

5. Maintenance
- Cleaning: Wipe the meter with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Battery Replacement: Replace the CR2032 battery when the display becomes dim or unresponsive. Follow the instructions in Section 3.1.
- Storage: When not in use for extended periods, remove the battery and store the meter in a dry, cool place away from direct sunlight and freezing temperatures.
- Leak Prevention: Regularly check the rubber rings and connections for wear and tear. Replace worn rubber rings and reapply sealing tape as needed to maintain a double leak-proof seal.

6. Troubleshooting
- No Display: Check if the CR2032 battery is correctly installed and has sufficient power. Ensure the protective plastic tab has been removed from the battery.
- Inaccurate Readings: Verify that the water flow direction is consistent with the setting direction (A-B) on the flow rate page for accurate measurement. Check for any leaks in the connections.
- Leaks: Ensure all connections are tightened properly. Reapply sealing tape if necessary. Check the rubber rings within the connections and battery cover for proper seating and damage.
- Screen Not Flipping: Ensure you are pressing the correct button (Flip/Reset button with circular arrow).
