2. Product Features

• Precise Water Measurement: Accurately measures water consumption, calculates water bills, and monitors pipe pressure. Data visualization simplifies water usage tracking and network quality assessment.
• Configurable Data Upload: The meter automatically uploads data to the Tuya app every 12 hours by default. This interval can be customized within the app to 1, 2, 4, 6, 8, 12, or 24 hours after connecting to a Tuya Gateway.
• Comprehensive Data Display: The Tuya Cloud Platform processes and stores water consumption data. Users can access hourly consumption details for the past 7 days and daily consumption for the past year via the app dashboard or Paas system.
• Remote Valve Control: Users can remotely control the meter's integrated valve through the app or Paas system. This feature is particularly useful for devices installed in outdoor or remote locations, allowing convenient operation from home.
• Valve Alarm System: In case of detected abnormalities, the water meter actively reports alarm information to the Tuya app. The app then pushes notifications to the user, prompting timely action. Certain abnormal alarms also support configurable automatic valve actions.

7. Maintenance

The BENEXMART Smart Ultrasonic Water Meter is designed for minimal maintenance. Follow these general guidelines:

• Regular Inspection: Periodically check the meter and its connections for any visible signs of damage, leaks, or corrosion.
• Cleaning: Keep the exterior of the meter clean and free from dust or debris. Use a soft, damp cloth for cleaning; do not use harsh chemicals or abrasive materials.
• Battery: The meter is typically powered by an internal battery. If a low battery indicator appears on the LCD or in the app, consult the manufacturer for battery replacement options. Do not attempt to replace the battery yourself unless explicitly instructed.
• No User-Serviceable Parts: Do not attempt to open or repair the meter yourself. Unauthorized tampering may void the warranty and could lead to malfunction or damage.

8. Troubleshooting

If you encounter issues with your BENEXMART Smart Ultrasonic Water Meter, consider the following:

• No Data in App:
  • Ensure the Tuya Zigbee Hub is online and properly connected to your network.
  • Verify the water meter is successfully paired with the Zigbee Hub in the Tuya app.
  • Check the data upload interval setting in the app. Data is not real-time by default.
  • Confirm the meter has power (check for LCD display activity).
• Valve Not Responding:
  • Check the meter's battery status in the app. Low battery may affect valve operation.
  • Ensure the Zigbee connection between the meter and hub is stable.
  • Verify your internet connection for remote control functionality.
• Alarm Notifications:
  • If the app receives an alarm (e.g., pipe burst, leakage, reverse flow), investigate the cause immediately.
  • Some alarms may trigger automatic valve closure; check the physical valve position.
• Physical Leaks: If you observe any physical water leaks around the meter, immediately shut off the main water supply and contact a qualified plumber for inspection and repair.

For persistent issues, contact BENEXMART customer support or your retailer.
