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 with two decimal places. The maximum measurable value is 999,999 L. If the unit is switched to gallons, the maximum remains 999,999 — note that 999,999 L equals approximately 219,969 GAL. After reaching the maximum, the counter resets to zero and begins measuring again. K-value setting interface appears when “00” is entered. “TOTAL” indicates total flow. Upon power-on, the main screen displays the total flow character. Measurement range: 0–999,999 L Temperature display range: –99°C to 999°C. Unit can be switched between Celsius (°C) and Fahrenheit (°F) by pressing the “+” key. Time/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), switchable by long-pressing the “+” key. Flow rate units: LPM (liters per minute) or GPM (gallons per minute), selectable via short press of the key. Battery indicator: Flashes when battery level is low, prompting replacement. Battery status is not displayed when power is sufficient. Power supply: Powered by three AAA batteries (batteries not included). Display color: White Material: Plastic Package includes: - 1 x Water flow sensor - 1 x Digital display Note: Color may vary slightly due to lighting and screen settings. Measurement tolerance: ±1–3 cm.
