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

This stuff works!!
Scent: Fragrance-Free - Standard Size
This set has been the absolute best shampoo, lotion, and ointment for my little one going through a tough spell of baby acne. The ingredient list is clean, and worked miracles quickly. Baby’s skin was so soft, the redness disappeared within days. After just the second wash I could really notice a difference. Thank you Tubby Todd!

Perfect gentle routine for newborn skin
Scent: Lavender Rosemary - Standard Size, Scent: Lavender Rosemary - Standard Size
We started using the Tubby Todd 3-Step Baby Bath & Skincare set when our baby was just weeks old, and it has been amazing for delicate newborn skin. The Hair + Body Wash is extremely gentle and doesn’t irritate or dry out the skin. It rinses clean and has a very mild, pleasant scent. The Everyday Lotion keeps our baby’s skin soft and smooth without feeling heavy or sticky. It’s perfect for daily use after bath time. The All-Over Ointment is great for extra-dry areas, especially around the cheeks and legs. It creates a protective barrier that helps prevent dryness, especially in cooler weather. We appreciate that this brand avoids harsh chemicals and focuses on clean, baby-safe ingredients. This routine has become part of our nightly bath time and has kept our newborn’s skin healthy and moisturized. Would absolutely recommend this to new parents looking for a safe, gentle skincare routine for their baby.

It didn’t work for my baby
Scent: Fragrance-Free - Standard Size
Update on my review: gave it 5 stars because the customer service is great!!! Thank you uso much! I’m sorry this product didn’t work out for my little one. But thank you for having a great customer service! I’ve been using the products for about a week now and haven’t noticed any improvement in my baby’s skin. I do appreciate that the ingredients are clean, fragrance-free, and that the ointment is thick and suitable for eczema. However, I’ve seen other reviews mentioning results within a few days, and unfortunately, that hasn’t been my experience. For me, it wasn’t worth the money. At first I thought my baby had ringworm but I took him to his pediatrician and she said it’s a mild eczema, I don’t want to do steroid lotion, I purchased this hoping it would help and it hasn’t

Before and after baby newborn acne
Scent: Lavender Rosemary - Standard Size, Scent: Lavender Rosemary - Standard Size
As a first-time mom, I was really stressed when my newborn developed baby acne. The doctor told me it’s normal, but it was still hard to see. I tried other products like Nutella, but unfortunately, nothing seemed to help. Then I decided to try this product — both the face ointment and the body lotion — and I’m so glad I did. My baby actually loves it! Unlike other lotions, it doesn’t feel cold on her skin, so she no longer cries when I apply it. The biggest difference was how quickly it worked. Within just 2 days, her acne improved so much. I was honestly surprised and relieved. I definitely recommend this product to other parents. For reference, my baby is Asian, and it worked very well for her skin.
