This Bluetooth Water Tank Gauge uses your phone as the display and shows the remaining water in liters or gallons, giving van owners and other mobile users a simpler way to monitor water usage with more confidence. Designed by Topargee in Australia, this gauge is built for freshwater tank monitoring in vans, RVs, trailers, boats, and off-grid setups. It works with pressurized and gravity-fed systems, installs inline on the water line, and does not require anything to be drilled into the tank. \u003cmeta charset=\"utf-8\"\u003eIf you prefer to use a mounted LCD screen instead of your phone, see the \u003ca href=\"https:\/\/orionvangear.com\/products\/flush-mount-water-tank-gauge\" title=\"Flush mount water tank gauge\" rel=\"noopener\" target=\"_blank\"\u003e\u003cstrong\u003eFlush Mount Water Tank Gauge\u003c\/strong\u003e\u003c\/a\u003e page. \u003c\/p\u003e \u003cdiv class=\"important-info\"\u003e \u003cdiv class=\"important-info__title\"\u003eImportant Info\u003c\/div\u003e \u003cp\u003eThis gauge tracks water use from the programmed starting amount.
