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

Best sunscreen brand! Fair, sensitive-skinned and rely on this
Style: SPF 50, Size: 5 Fl Oz (Pack of 1)
Alba Botanica is my favorite brand for sunscreen products and it checks all the boxes on my list: Excellent long lasting coverage, fine mist spray and easy coverage cream versions, great for my sensitive skin (no breakouts- I do NOT use it on my face though), the Hawaiian fragrance is pleasant, it’s reef safe (a big one for me as a snorkel/dive aficionado), and organic ingredients. The large size lasts 5 full days when on a boat all day in the Carribbean, and I only apply it twice (once in morning, and again midday.) I have fair skin, and I never burn. The spray version is, by nature of its aerosol capacity, a bit drying on the skin, but this is to be expected, and it creates a long lasting barrier. The cream version is a wonderful emollient, although not quite as long lasting. Best deal is only in the summer season at CostCo for a 2 pack... in my searches, Amazon has the best deal otherwise.

In most of all circumstances, this works
Style: SPF 50, Size: 6 Fl Oz (Pack of 2)
For Summer time and when playing and working in the sun, this is my go to sunscreen! I love how it is more natural than all the other ones out there. I have been sort of a spray on sunscreen connoisseur and this is the one that is my favorite. Also, if I have gotten a burn and put this on it, I believe it helps start the healing process on the burn I got. This is at least what I experienced multiple times last year. The only circumstance that this sunscreen fails miserably is in the Caribbean. I recently went on a cruise to that region and applied this sunscreen and it became evident that this and the other brands of spray on sunscreen do not work in Caribbean sun. The only sunscreen that works is the lotion based stuff that you rub into your skin. I have also consulted with friends on spray on sunscreen in the Caribbean and they all fail as well. So, this is why I say that it works in almost every circumstance.

spray nozzle needs work.
Style: SPF 50, Size: 6 Fl Oz (Pack of 2)
I purchased 3 of these cans. Only one of them worked and that one was ok. Sprayed well, smelled good and and protected my skin and even though it was hard to press it to work, we WERE able to use it, but the other three .............? They would not rotate to the unlock position, therefore they would not spray. My husband and I tried everything to get it to rotate. It seems both the top and bottom ring spin around effectively doing nothing. So to pay almost $40 for only one can to work is definitley not worth the money. Buy somewhere else.

Great product! Highly recommend! Worth the money
Style: SPF 50, Size: 6 Fl Oz (Pack of 2)
Our family absolutely loves Alba sunscreen! It’s light, not super greasy, and smells really good. Everytime I see it on sale, I buy more of it! My husband is a red head, and he has to wear sunscreen all the time, and he prefers Alba brand over any others. Great Product!
