3. Operating Instructions
The RESTMO Water Flow Meter features a single button for easy navigation through its four measurement modes:

- Total Mode: Displays the cumulative total water consumption since the last reset. This mode is ideal for tracking overall water usage over extended periods.
- Flow Mode: Shows the real-time water flow rate in Gallons Per Minute (GPM) or Liters Per Minute (LPM). To switch between gallons and liters, long-press the button while in Flow Mode.
- Consumption Mode: Displays the water consumption from the last single watering session. This allows you to see how much water was used in your most recent task.
- Average Mode: Calculates and displays the daily average water usage over the last seven days, starting from the next day after activation.
Press the single button to cycle through these modes. The display will clearly indicate which mode is active.
4. Maintenance
Battery Installation/Replacement:
The water flow meter uses a CR2032 3V button cell battery. Replace the battery when the low battery symbol appears on the display.
- Unscrew Cap: Locate the battery compartment cap on the back of the meter. Unscrew the cap in the direction of the "unlock" symbol. The cap has a swivel bar for easy grip.
- Install Battery: Insert a new CR2032 battery with the positive (+) side facing outwards (towards you).
- Secure Battery: Ensure the battery is seated correctly. No need to adjust the position of the metal piece inside the battery compartment.
- Screw Cap: Screw the cap back on in the direction of the "lock" symbol until it is secure.

General Care:
- Clean the exterior of the meter with a soft, damp cloth. Do not use abrasive cleaners.
- While the meter is IPX6 waterproof, avoid submerging it in water.
- Store the meter in a dry place when not in use, especially during freezing temperatures to prevent damage.
5. Troubleshooting
If you encounter issues with your RESTMO Water Flow Meter, consider the following:
- No Display/Faint Display: Check the battery. Replace it if it's low or depleted. Ensure the battery is inserted with the correct polarity.
- Inaccurate Readings: Ensure the meter is securely connected and there are no leaks at the connections. Verify that the water flow is consistent and not turbulent. The measurement tolerance is less than 5%.
- Leaks at Connections: Ensure all connections are hand-tightened. Check the rubber washers (gaskets) inside the connections for proper seating and damage. Replace if necessary.
- No Flow Detected: Ensure water is actually flowing through the meter. Check for blockages in the hose or nozzle.
