The RiVöt TankMaster is a wireless Bluetooth + Wi-Fi tank monitoring system designed for RVs and boats. Each TankMaster module monitors a single tank — one unit per tank — providing continuous level readings through a set of contactless threshold sensors. The system eliminates the need for traditional in-tank probes or floats, offering a cleaner, maintenance-free solution that’s simple to install and easy to use.
Each TankMaster supports up to four contactless sensors, allowing you to detect tank levels at multiple points (for example: 25%, 50%, 75%, and full). These sensors mount externally to the tank wall and use a capacitive sensing technology to measure fluid presence without any physical contact with the liquid inside.
The TankMaster connects wirelessly to the RiVöt TankMaster mobile app via Bluetooth for setup and local monitoring. The system can also connect over Wi-Fi for extended range. Once connected, you can view real-time tank levels, historical data, and customizable alerts directly from your phone or tablet.
Power is supplied through a standard USB-C connection from a 5 V DC USB power source, such as an RV’s 12 V-to-5 V DC converter, a vehicle USB port, or a USB battery pack.
Together, the TankMaster modules create a complete, modular tank monitoring solution — scalable, easy to install, and built for modern connected RVs.
System Components and Overview
Your RiVöt TankMaster system arrives pre-assembled and ready for configuration.
Each kit includes everything needed to monitor a single tank — one TankMaster unit per tank — with all sensors pre-connected.
- TankMaster Sending Unit – The main electronics module that manages sensors and communicates via Bluetooth and Wi-Fi.
- Four Contactless Threshold Sensors – Pre-wired and ready to mount. These adhere to the outside of the tank to detect fluid levels without drilling or contact.
- USB Power Cable – Used to supply 5 V DC power to the TankMaster sending unit from a customer-supplied 5 V DC USB power source (such as an RV’s 12 V→5 V DC converter, vehicle USB port, or USB battery pack).
- Adhesive Mounting Pads – 3M double-sided adhesive disks used to attach the sensors securely to the tank surface.
Note: No AC USB power adapter is included or required. The system is designed for use with customer-supplied 5 V DC USB power sources commonly found in RVs.
