Fathom Smart RV
- FM548FR
- Water Tanks
- Monitoring System
- Fathom
- No Display
- Monitors Only
Check fresh, gray, or black tank levels without a sensor sitting in the liquid. This top-mounted Fathom radar sensor reads through plastic tank walls and sends readings to a compatible RV-C/CAN system.
Highlights
- Avoid Dirty In-Tank Probes: FMCW radar reads through plastic tank walls without sitting in water or waste.
- Track Changing Water Levels: Measures gradual level changes in the tank, with approximately 1/8" accuracy.
- Use Your RV-C Monitoring System: Native RV-C/CAN sends tank readings to compatible RV controls.
- Configure It for Your Tank: Set tank type, depth, instance, and up to 5 geometry regions over RV-C.
- Check Your Mounting Spot: Sensor needs tank-top access and a suitable position over the deepest section.
- Skip Sensor Maintenance: No cleaning, battery changes, adjustment, or recalibration required.

Features to know about
Measure Tank Levels Without Going Inside
Instead of putting a probe in your fresh, gray, or black tank, this Fathom radar sensor mounts on the outside top of a compatible plastic holding tank. FMCW radar measures the liquid level through the tank wall, tracking changes as the tank fills or empties. It's a way to monitor more than just empty and full without anything sitting in the water or waste.
Connect to Your Compatible RV-C System
The sensor communicates directly over RV-C/CAN through a 4-wire power and communication connection. Tank type, depth, instance, and up to 5 geometry regions can be configured over RV-C to match your setup. Confirm that your RV monitoring system supports the sensor before ordering.
Stick It to the Tank and Skip the Usual Sensor Upkeep
3M 300 LSE peel-and-stick adhesive mounts the sensor on the exterior top of a plastic tank. Make sure you can reach and prepare that surface, with a suitable spot over the deepest section and away from rounded edges. The housing resists moisture and corrosion, and integrated strain relief secures the cable. There's no battery to replace or sensor to clean, adjust, or recalibrate.
