This water flow meter has solid brass inlets and outlets with metal threads, which are sturdy, durable and long-lasting, causing no trouble even with frequent hose or faucet installation and disassembly. Equipped with an easy-to-read LCD screen and one-key control button, it easily displays and tracks water consumption and flow of your outdoor garden hose, offering 4 measurement modes. A short button press switches between flow rate, water consumption, average and total modes: flow rate mode shows real-time flow, water consumption mode shows last usage, average mode shows weekly daily average water consumption (calculated from the second day), and total mode shows overall usage. A long press in flow rate mode switches units (gallon/liter), while in other modes it resets data. The LCD enters sleep mode automatically if there is no operation or water flow for 1 minute. Built-in Hall sensor and integrated circuit chip ensure accurate measurement with an error of less than 5%, ideal for measuring water use and preventing over-watering. Made of high-quality, durable high-strength ABS material, it is weatherproof and UV-resistant, effectively withstanding sunlight and rain, and its IPX6 waterproof rating ensures stable outdoor performance. Note: Do not open the battery compartment cover with wet hands, keep hands dry when installing batteries, insert batteries in the correct direction, and lock the cover tightly after installation.
