RV Water Tank Monitor System Probeless Adhesive Sensors with Smart M Board and 15' Wire Extension | RV Level Monitor System | Water Tank Level System | Probless Monitoring System
What This Product Is
This product is a complete monitoring kit that uses sticky, external sensors to read tank levels and sends those readings to a central control panel with label lights. You get a Smart M board that acts as the brains of the system, adhesive sensors that mount on the outside of your tanks, and long wire extensions so you can place everything where it’s most convenient.
What’s Included
You’ll get adhesive sensors that mount on the outside of tanks, a Smart M control board with a display panel, and a 15-foot wire extension to help connect sensors placed farther away. The kit typically includes mounting hardware and wiring instructions, giving you everything needed for a basic DIY installation.
How It Works
The sensors adhere to the tank exterior and use capacitance or similar non-invasive sensing to estimate liquid levels, transmitting signals to the Smart M board. The board processes these signals and lights labeled indicators on the control panel so you can quickly see fresh, grey, and black water levels as well as battery and LPG status, and control the pump and heater.
Installation Experience
You’ll appreciate how approachable the installation is, especially if you’re the kind of person who likes DIY improvements. Because the sensors stick onto the tank instead of piercing it, you avoid the messy and risky steps tied to in-tank sensors.
Tools and Prep
You’ll need basic tools like isopropyl alcohol, a clean rag, possibly a drill for mounting the control panel (not the tank), and zip ties or adhesive mounts for wire management. Make sure you have enough time to clean the tank surface thoroughly so the adhesive can bond well — a clean surface is critical for reliable readings.
Step-by-Step Installation
- Identify tank locations and map sensor placement: You’ll locate fresh, grey, and black tanks and plan sensor rows so each sensor corresponds to a meaningful level mark.
- Clean tank surfaces: Wipe with isopropyl alcohol and allow to dry fully so the adhesive sticks properly.
- Stick sensors to the outside of tanks: Line them up vertically (or according to instructions) to represent empty-to-full progression. Press firmly for a minute or two to ensure a good bond.
- Route wires to the Smart M board: Use the 15′ extension as needed and secure cables away from moving parts or heat sources.
- Mount and wire the control panel: Attach the display panel in a convenient spot and connect the Smart M board to power, sensors, and optional accessories like a pump or heater control.
- Calibrate and test: Power up, follow calibration steps if required, and fill/empty tanks gradually to verify readings match real-world levels.
Performance and Accuracy
You’ll get reliable level estimates that are quite accurate for everyday RV use, provided sensors are mounted correctly and the tank exterior is compatible. The adhesive, probeless design may not match the micron-level precision of inside-tank probes in all edge cases, but for practical decisions — like deciding whether to dump the black tank or top off fresh water — it’s more than sufficient.
Water Level Monitoring
The system reports on fresh, grey, and black water levels using labeled lights so you can quickly know which tank needs attention. You’ll like how simple the visual feedback is: instead of squinting at complex gauges, you get clear, labeled status lights that intuitively communicate tank status.
LPG and Battery Monitoring
Beyond water tanks, the control panel reads LPG and battery levels so you can manage power and fuel resources without guessing. You’ll benefit from having that information consolidated on one control panel, which makes trip planning and campsite decisions easier.
Pump and Heater Control
You can control your water pump and water heater through the panel, giving you a central point to manage essential systems. Instead of toggling switches scattered around the RV, you’ll appreciate having control and monitoring consolidated, which is more convenient and reduces the chance of missed steps when shutting down or preparing to move.

Troubleshooting and Maintenance
You’ll likely experience smooth operation, but there are common issues you should be ready to fix. Most problems trace back to surface prep, wiring, or interference from nearby metal components, and they’re usually straightforward to resolve.
Common Issues and Fixes
If a sensor reads erratically or not at all, first check the adhesive bond and the wiring connections; reseating the connector or reapplying the sensor with proper surface prep often fixes the problem. You should also test the sensor placement by moving it slightly to see if readings stabilize — sometimes minor adjustments in position or orientation make a big difference.
Long-Term Care
You’ll want to periodically inspect sensor adhesion and wiring during routine RV maintenance, especially after long trips or extreme weather changes. If an adhesive starts to fail, clean the area and reapply with replacement adhesive pads or a recommended marine-grade adhesive to keep performance consistent.
Comparison with Piercing Sensors
When deciding between probeless adhesive sensors and traditional in-tank probes, you’ll weigh convenience, risk, and accuracy. Probeless sensors minimize installation risk and maintenance headaches, but probes can offer higher absolute accuracy for certain applications.
Advantages of Probeless Design
The main benefits are that you won’t need to cut into tanks or install fittings, which reduces leak risk and installation complexity; plus, sensors are easy to reposition or replace. You’ll appreciate that you can retrofit older RVs without major modifications and that maintenance tends to be less invasive.
When Piercing Might Still Be Better
If you need laboratory-level accuracy or have metal tanks that block capacitive readings, in-tank probes may be the better choice. You’ll consider probe-based sensors if your priority is maximum precision or if you have a tank’s internal geometry that confounds external sensing.
Real-World Use Scenarios
You’ll find this system helpful in everyday RV life, from weekend trips to extended boondocking. The practical benefits show up in multiple scenarios where knowing tank states and controlling systems quickly matter.
