When water flow is detected, the display shows animated water droplets. It displays total water consumption and flow rate. Total water consumption is shown in liters (L) and gallons (GAL). Values below 10,000 L (or GAL) are displayed with two decimal places. The maximum measurable value is 999,999 L. If the unit is switched to gallons, the counter resets at 219,969 GAL. After reaching the maximum, the counter resets to zero and begins measuring again. K-value setting interface: Press the appropriate button to enter K-value setup (display shows “00”). Total flow indicator (“TOTAL”) appears on the main screen when the system is powered on. Measurement range: 0–999,999 L. Temperature display range: –99°C to 999°C. Units can be switched between Celsius (°C) and Fahrenheit (°F) by pressing the “+” key. Time and flow rate display: When water is flowing, the display automatically shows real-time flow rate. When no flow is detected, it displays total operating time in days (DAY) or hours (HOUR), selectable by long-pressing the “+” key. Flow rate units: Liters per minute (LPM) or gallons per minute (GPM), switchable by short-pressing the designated key. Battery indicator: Flashes when battery level is low, indicating replacement is needed. Battery status is not displayed when power is sufficient. Power supply: Powered by three AAA batteries (batteries not included). Color: White Material: Plastic Package includes: 1 × Water flow sensor 1 × Digital display Note: Color may vary slightly due to lighting and screen settings. Measurement tolerance: ±1–3 cm.
