When water flow is detected, the stream head animation shows water droplets along with total water consumption and flow rate. Total water consumption is displayed in liters and gallons, with accuracy up to two decimals for values under 10,000. The maximum measurement is 999,999 liters. The K value setting interface appears as "00" for adjustments. The temperature range is -99 to 999 degrees Celsius and can be switched between Celsius and Fahrenheit by pressing the "and" key. While water is flowing, the display shows flow rate otherwise, it shows total time in days and hours, with units switchable by long pressing the "and" key. The flow rate can be shown in "l or min" or "gallon or min". A battery alert flashes when the battery is low, and the system operates on three AAA batteries (not included).
