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

Great Fit, Lightweight, and Totally Quiet
Size: 11, Color: New Black05
Great fit and very comfortable once you pick the right size. Lightweight, breathable, and completely silent on hard floors. No squeaks or “suction” sounds like some reviews claimed. Normal packaging, normal opening, no issues at all. Excellent value for the price.

Most comfortable shoes I've ever worn
Size: 11, Color: New Black05
First off, I was not expecting much buying a no-name shoe online, especially for the price. Boy was I in for a surprise... I've owned these for almost a full year, and can confidently say these are the most comfortable shoes I've ever worn. I normally wear a size 11 and these fit me perfectly. Prior to this the most comfortable shoes I had were some Cole Haans with the Nike air technology. These shoes are so lightweight, so comfortable, I can wear them all day long without feeling a thing. Whenever I (rarely) need to wear a different pair of shoes, I am immediately reminded of how much I used to hate wearing shoes and couldn't wait to take them off. Based on the price, I expected them to wear down quickly. However they are still going strong. Running, hiking, long walks, biking, worn to office / casual events. These shoes have been soaked in mud multiple times, but clean up easily by just throwing them in the washing machine and then the dryer. The soles and the insoles have both worn down a bit over the past year; at this rate I expect to get 1.5 to 2 years out of them before needing to be replaced. So far I must have put at least a thousand miles on these shoes based on how much I wear them. They look good too. I have the all-black pair, and they look decent with jeans and a button up shirt for a night out, but also look natural in an athletic setting with shorts and no socks. Very versatile and subtle. Now for the cons, which are minor. The pattern on the bottom of the sole is prone to some squeaking/suction sounds at first. However after about a month some of the ridges wore down just enough that it was no longer a problem. Second: they are not as breathable as I would have liked. For example, when running or biking, you don't feel any air on your feet. Wearing them out in the sun on a hot summer day, your feet will get a bit stuffy. In fact the fabric is woven tight enough that I wear them in the winter and in the rain, and don't get too cold or wet. So I do wish they made a more breathable version for summer time use. All that being said, these are still the best pair of shoes I've ever had. Ultra light weight, comfortable, and can be worn all day long without feeling any fatigue whatsoever. --- UPDATE: It's been 1 year and 9 months, and the soles on these shoes are fully worn out and ready for replacement. Considering I've put between 1,000-2,000 miles of walking in these, that's pretty good. If anyone from Feethit is reading this, here are my top suggestions to perfect this shoe: 1) Easy fix - change the tread pattern. The current pattern causes suction cup effect on hard floors until it starts to wear down. Simply add some gaps in the circle pattern in the tread and it will remedy that issue. 2) Most importantly, put a thin piece of durable rubber on the bottom of the sole. The sole does wear down after some time and lose traction, especially on smooth wet floors (e.g. in the rain, in a kitchen, etc.). A thin piece of durable rubber would add more traction and also extend the life of the cushion-like sole (which is fantastic, don't change it!). This would easily be worth an extra $5-$10 in the price.

Nice shoes, despite the squeak and inconsistent sizing
Size: 12, Color: Black White 05
Excellent shoes at this price point. Quite comfortable. They do tend to have a nasty squeak on tile floors, sort of like a suction cup being engaged and disengaged. I bought the navy blue and went back and bought the black. I have to say that the size varied greatly. With the second pair, I have to be sure to wear thin socks and even then, I struggle to get them on, despite having an extremely narrow foot. I'm not sure that a person with an average width foot could wear them. Buyer beware. You may need to go up a size.

My second pair and what they look like after 2 years
Size: 10.5, Color: New Black05, Size: 10.5, Color: New Black05
I wanted to write a review on these shoes. This is my second purchase. I bought the first pair 2 years ago and the bottoms started wearing out, after all it was 2 years. I read reviews saying that they did not hold up well. My pictures show before and after. The reason I purchased again is because I am impressed with the quality and comfort for the money.
