When a flow of water is detected, the stream head animation will begin to show the water droplets.total water consumption, flow rate display.The total water consumption is expressed in litres of L and gallons of gallons, and the unit is passed. When the total water consumption is less than 10000L (or GAL) will be accurate to two decimal , when the total water consumption is 9999.99 L (or GAL) The decimal point will be hidden. The maximum measurement 999999L (Note: If the upgrade, if the unit is set.Into the GAL, also count 999999L clear 0, that is, remember to 219969GAL clear 0), after more than.Remeasurement starts at 0.K value setting character (K SETTING) The K value setting character will be displayed when entering the interface number: 00 for the K value setting interface (K SETING) Show it Total Traffic Character (TOTAL).When the system is powered on, the total flow character is displayed on the main screen.three, settings and interface : Plumbing Measurement Range: 999999L the temperature The temperature display range is -99-999 Celsius. Unit C is Celsius and F is Fahrenheit. Temperature unit It can be switched by pressing the "+" key. the use of time / flow rate display When there is water flow, it will automatically jump to the flow rate display, and when there is no water flow, the total time will be displayed. Total time unit DAY Indicates , indicates hours, and time units can be switched by long pressing the "+" key. temperature display Use time/flow rate display Water flow painting display Total flow character character TOTAL Battery indication Total water consumption The flow rate unit LPM is "l/min", GPM is "gallon/min", can be short-pressed by "-" Key switch. battery prompt The battery alert flashes when the battery is low, prompting the user to replace the battery. In electricity It will not be displayed if there are sufficient quantities. water flow painting how to set the system operating mode Use the battery three AAA battery interface to power the system.(Not include battery) the main interface and the main interface settings colour:white Material:plastic Package Contents: 1 * water flow sensor 1 * digital display Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
