When water flow is detected, the display shows animated water droplets and indicates total water consumption and flow rate. Total water consumption is displayed in liters (L) and gallons (GAL), with measurements accurate to two decimal places when under 10,000L (or GAL). The maximum measurable capacity is 999,999L (equivalent to 219,969 GAL), after which the counter resets to zero for re-measurement.K Value Setting (K SETTING): The K value setting interface appears when entering code 00. This allows adjustment of the K value parameter.Total Flow Display (TOTAL): Upon powering on, the total flow reading is shown on the main screen.Measurement Range: Up to 999,999LTemperature Display: Shows temperature from -99C to 999C. Units can be switched between Celsius (C) and Fahrenheit (F) by pressing the "+" button.Usage Time / Flow Rate Display: When water is flowing, the screen automatically displays flow rate. When no flow is detected, it shows total usage time in days and hours. Time units can be switched by long-pressing the "+" button.Flow Rate Units: Selectable between LPM (liters per minute) and GPM (gallons per minute) via short press of the control button.Battery Indicator: Low battery warning flashes when power is low, indicating need for battery replacement. The indicator does not appear when battery is fully charged.Power Supply: Requires three AAA batteries (not included).Product Details: Color: White Material: Plastic Package Includes: 1 x Water Flow Sensor 1 x Digital Display Unit Note: Light and screen differences may cause slight color variation between image and actual item. Measurement error tolerance is +/- 1-3 cm.
