Using advanced ultrasonic technology, this sensor reads levels down to 0.25 mm (0.01 inch), providing the data integrity needed for inventory control, safety compliance, and operational efficiency. Its long-range Bluetooth (BLE) connectivity integrates directly with the Tank Check or Co-Pilot app, transforming your smartphone or tablet into a centralised monitoring dashboard.\u003c\/p\u003e \u003cp\u003eUnlike conventional float-based or capacitive sensors, the TD40 mounts externally to the tank bottom, eliminating contact with the liquid. This non-invasive design reduces corrosion risk, simplifies installation, and ensures consistent performance across a wide range of tank heights up to 4.88 metres (16 feet). Whether you are managing a single residential LPG tank or a fleet of commercial vessels, the TD40 provides reliable, repeatable measurements without the maintenance burden of traditional probes.\u003c\/p\u003e \u003ch3\u003eKey Technical Advantages\u003c\/h3\u003e \u003cul\u003e \u003cli\u003e \u003cstrong\u003eSub-millimetre resolution:\u003c\/strong\u003e Measures liquid levels to 0.25 mm, enabling precise inventory tracking and leak detection.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eExtended battery service:\u003c\/strong\u003e Powered by 2x AA Energizer Ultimate Lithium cells, delivering up to 5 years of operation for minimal field intervention.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eBoosted Bluetooth range:\u003c\/strong\u003e Long-range BLE ensures stable data transmission through tank walls and across typical installation distances.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eMulti-commodity support:\u003c\/strong\u003e Select propane, butane, water, or custom liquids directly in the app for automatic volume calculations.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eCloud-enabled data:\u003c\/strong\u003e AWS-powered backend allows remote monitoring, historical trending, and multi-user access via the Co-Pilot platform.\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eVictron integration ready:\u003c\/strong\u003e Seamlessly connects with Victron GX devices for unified energy system monitoring.\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eInstallation and Integration\u003c\/h3\u003e \u003cp\u003eThe TD40 requires a 50.8 mm (2-inch) threaded port or a 50.8 mm diameter hole cut into the tank top. This standardised footprint simplifies retrofitting into existing tank infrastructure. Once installed, the sensor pairs with the free Tank Check or Co-Pilot app, available for iOS and Android. The app provides real-time level readings, low-level alerts, and usage history, helping you avoid run-outs and optimise refill scheduling.\u003c\/p\u003e \u003cp\u003eFor off-grid and mobile applications, the TD40’s low power consumption and robust BLE link make it ideal for caravans, RVs, and marine vessels where reliable tank monitoring is critical but access is limited. The sensor’s solid-state design withstands vibration and temperature extremes, ensuring dependable operation in harsh environments.\u003c\/p\u003e \u003ch3\u003eWhy Choose Ultrasonic Over Traditional Sensors?\u003c\/h3\u003e \u003cp\u003eTraditional mechanical float sensors are prone to sticking, corrosion, and inaccurate readings due to sludge or sediment. Capacitive probes require tank wall penetration and are sensitive to liquid dielectric changes. The Mopeka TD40’s ultrasonic pulse technology measures the time-of-flight from the sensor to the liquid surface, unaffected by liquid composition, temperature stratification, or tank material. This results in a maintenance-free solution that maintains accuracy over years of service, reducing total cost of ownership and operational risk.\u003c\/p\u003e \u003ch3\u003eApplications\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eCaravan and RV fresh water and LPG tanks\u003c\/li\u003e \u003cli\u003eMarine fuel and water storage\u003c\/li\u003e \u003cli\u003eOff-grid residential propane and water systems\u003c\/li\u003e \u003cli\u003eIndustrial chemical and process liquid inventory\u003c\/li\u003e \u003cli\u003eTiny home utility monitoring\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eDownload the App:\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\u003ca href=\"https:\/\/play.google.com\/store\/apps\/details?id=installer.test\u0026amp;hl=en_AU\u0026amp;pli=1\" target=\"_blank\"\u003e \u003cdiv style=\"text-align: left;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0602\/3918\/3933\/files\/google_play.jpg?v=1776311038\" alt=\"Download Mopeka Tank Check on Google Play\" style=\"margin-bottom: 16px; float: none;\" width=\"125\" height=\"44\"\u003e\u003c\/div\u003e \u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/apps.apple.com\/au\/app\/mopeka-co-pilot\/id1612507006\" target=\"_blank\"\u003e \u003cdiv style=\"text-align: left;\"\u003e\u003cimg height=\"46\" width=\"128\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0602\/3918\/3933\/files\/app_store.jpg?v=1776311064\" alt=\"Download Mopeka Co-Pilot on the Apple App Store\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e \u003c\/a\u003e\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eFor detailed installation instructions, please refer to: \u003ca href=\"https:\/\/mopeka.freshservice.com\/support\/solutions\/articles\/20000038126-Mopeka-TD40-Install-Instructions\" target=\"_blank\"\u003eMopeka TD40 Install Instructions\u003c\/a\u003e\u003c\/p\u003e \u003ch3\u003eTake Control of Your Tank Monitoring\u003c\/h3\u003e \u003cp\u003eEquip your system with the Mopeka TD40 Ultrasonic Tank Level Sensor and gain the precision and reliability your operations demand.
