Mopeka TD40 Ultrasonic Bluetooth Tank Level Sensor: Precision Monitoring for Critical Liquid Assets

Engineered Accuracy for Demanding Tank Level Applications

The Mopeka TD40 Ultrasonic Tank Level Sensor delivers high-resolution liquid measurement for professionals managing propane, LPG, water, and other stored liquids. 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.

Unlike 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.

Key Technical Advantages

  • Sub-millimetre resolution: Measures liquid levels to 0.25 mm, enabling precise inventory tracking and leak detection.
  • Extended battery service: Powered by 2x AA Energizer Ultimate Lithium cells, delivering up to 5 years of operation for minimal field intervention.
  • Boosted Bluetooth range: Long-range BLE ensures stable data transmission through tank walls and across typical installation distances.
  • Multi-commodity support: Select propane, butane, water, or custom liquids directly in the app for automatic volume calculations.
  • Cloud-enabled data: AWS-powered backend allows remote monitoring, historical trending, and multi-user access via the Co-Pilot platform.
  • Victron integration ready: Seamlessly connects with Victron GX devices for unified energy system monitoring.

Installation and Integration

The 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.

For 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.

Why Choose Ultrasonic Over Traditional Sensors?

Traditional 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.

Applications

  • Caravan and RV fresh water and LPG tanks
  • Marine fuel and water storage
  • Off-grid residential propane and water systems
  • Industrial chemical and process liquid inventory
  • Tiny home utility monitoring

For the price it was a winner
Size: 23" x 23", Color: Beige
One of my pups likes to attack his beds. This is a fine replacement at a decent price. I will say I was thrown for a loop buy the way it comes in the package. Once properly assembled the dogs took to it no problem.
