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). When total consumption is less than 10,000 L (or GAL), it displays up to two decimal places. At 9,999.99 L (or GAL), the decimal point is shown. The maximum measurable value is 999,999 L. If the unit is switched to gallons, the counter resets at 219,969 GAL (equivalent to 999,999 L). After reaching the maximum, the measurement resets to zero and restarts.K-value setting interface: When “00” appears on the screen, it enters the K-value setting mode.Total flow indicator (TOTAL): Appears automatically on the main screen when the system is powered on.Plumbing specifications: - Measurement range: 0–999,999 L - Temperature range: –99°C to 999°C - Temperature units: °C or °F — switchable by pressing the “+” key Time and flow rate display: - When water flows, the display automatically shows real-time flow rate. - When no flow is detected, it displays total operating time in days (DAY) or hours — switchable by long-pressing the “+” key. Flow rate units: - LPM = liters per minute (L/min) - GPM = gallons per minute (GAL/min) - Switch between units using a short press of the designated key Battery indicator: - Flashes when battery level is low, indicating replacement is needed. - No battery indicator is shown when power is sufficient. Power supply: - Powered by three AAA batteries (batteries not included). Display color: White Material: Plastic Package includes: - 1 × water flow sensor - 1 × digital display Note: Color appearance may vary slightly due to lighting and screen settings. Measurement tolerance: ±1–3 cm.
