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

Read all of his books, you won't be dissapointed.
Format: Paperback
I love Dr. Heiser books, but I wanted to step back from the spiritual realm and reconnect with scripture again. This book is light, easy to read, and like all his content, so eye opening. I am alway slapping myself in the forehead and wondering how I didn't know or notice things. "I Dare You Not to Bore Me With the Bible" is another of his books that I'm reading simultaneously. If you want to go deeper in Bible Study, this is the book. It's helped me forgive a lot of the Bible "hangups" I have that were very cultural or significant for reasons I missed. Get those 2 books (this and the one I mention above), and then when you're ready to really have your understanding of G-d and the Bible blown out of the water, move on to Unseen Realm, Reversing Hermon, Supernatural, and all of the others. If you desire to understand the Bible, and not just show up on Sunday, read everything by Dr. Michael Heiser, his website is a great resource too. So grateful for the work he does.

Excellent tool for gospel workers!
Format: Kindle
For those of us who want to contextualize the gospel in pagan contexts, Dr. Michael S. Heiser helps us get beyond our own cultural context to the ancient cultural context of the Bible itself. One could spend years and years researching the ancient contexts of the Bible, but for workers with families and careers other than Dr. Heiser's, the time needed would far exeed what is practical. Thankfully, there is a solution: Dr. Heiser has done a lot of the distilling needed to grasp the basic cultural and linguistic backgrounds of the Bible writers. After presenting the Unseen Realm, Reversing Hermon and I Dare You Not To Bore Me With The Bible, he has done one better here in the Bible Unfiltered. Why do I say better? Well, I would say that as time has gone on, Dr. Heiser's ability to communicate complex topics for the average layman has improved markedly. Get this book, let it whet your appetite, and then please do get Unseen Realm and Reversing Hermon. They will help you to understand the Bible, contextualize the gospel, and offer an entrance to a fantastic intellectual and spiritual journey of a lifetime.
