Digital flow meter display only ,must connect a flow sensor 3Vdc NPN pulse signal can to run. if you would need the full kit ,please visit our store other links to choose. Shipment : only Display x 1 pcs , For flow sensor connection, buy flow sensor separately. Shipping not with Batteries . LCD display Digital flow meter temperature measuring flow sensortotal Liter / Gal can measure temperature ( C / F ) , flow rate , total flow L / Gal . Digital Flow Meter Manual Instruction total detail 1.Key paddefinition Keypadfrom the left to the right, respectively, the keyset "SET", the keyplus "+", the key minus"-". 2.Display manual 1)Temperature: The current interface number is displayed under other interfaces: 00 indicates the K value setting interface (K SETING). 3) Power noted: The power prompt icon will be displayed when the battery is low and flashing.Reminder the user to replace the battery. In the case of adequate power it is not displayed. 4)Faucet animation (flowmeter only) When detectedwater is flowing, the faucet animation will begin to show water droplets 5) Total water consumption, flow rate display The total amount of water used in the unit L represents the rise, GAL means gallons, the unit can pass. When the total water consumption is less than 10000L (or GAL) will be accurate to the decimal point after the two, when the total water consumption is greater than 9999.99 L (or GAL) will hide the decimal point after the value. The maximum measurement 999999L (Note: to l as the quasi, if the unit set to GAL, is also full of 999999L then cleared to 0, that is, after the record 219969GAL then cleared to 0), after more than it,then from 0 to re-measure. 6) K SETTING---is for adjusting if measurement error of different flow sensor K value setting characters will be displayed when entering the K value setting interface. 7) Total flow character (TOTAL) (flowmeter only) When the system is operating in the flowmeter mode, the total flow character is displayed in the main interface. 3 . Settings and interface description 1)The main interface and settingsunder the main interface (1) The main interface will display the characters TOTAL, total water consumption, temperature, total use time. (2)Press the "SET" key in the main interface to set the total usingtime. Press the "SET" key on hold ,the first number of time will flash, short press "+" flashing numbers will be added; short press "-" flashing numbers will be reduced by 1; short press "SET" key to switch to The next digit. Set long after long press "SET" button to save the settings. Note: When setting the total usingtime, the default is set in hours. The total elapsed time in the flowmeter mode and the total usingtime in the barometer mode are independent. 2) K value setting interface and setting of K value setting interface (flow meter mode only) When the system is in flowmeter mode, press "SET" key in the main interface to jump to K value setting interface. K value setting interface will display the character "K SETTING", interface number 00, K value.Press the "SET" key to set the K value under the K value setting interface. Press the "SET" button to turn the first digit of the K value will flash, short press "+" flashing number will increase; short press "-" flashing number will be reduced by 1; short press "SET" key to switch to the next Number of bits. after long press "SET" button to save the settings. Different Flow sensor output pulse number different, when display show volume is moredifferent from measurement, adjust K setting number (K value) Ifthe actual flow is large, the K value is adjusted to be small.Ifthe actual flow isless, the K value is adjusted to be large. 4 .Others 1). System hibernation mechanism (flowmeter only) In the use of battery interface power supply, in order to save energy and improve battery life, the system in the absence of operation and no water flow will enter the dormant state. After entering the sleep state, the display will automatically jump to the main interface and keep the display function. When there is water flow automatically wake up into the measurement state. 2).Total water consumption is reset on TOTAL table, press SET more than 3 seconds, number flashing, adjust all numbers to zero. TOTAL Not show the number after the decimal point. Press Set to save the reset. How To check K setting value is which number? If measure Total flow different of real total flow L/ Gal , adjust the K setting number. _x000D_
