PTLevel Wireless Tank Level Monitor

PTLevel offers two notification points for high and low levels via email and SMS, plus sharing with your water provider. It’s designed to operate in extreme temperatures from -40 to 85 degrees Celsius and runs on four AA batteries for years of low-maintenance operation. Best for homeowners and small operations that need straightforward alerts and a simple power setup. Caution: verify battery availability and replacement in remote locations to avoid downtime.
TankMaster – Wireless RV Tank Monitoring System

TankMaster consolidates fresh, gray, and black tank monitoring for RVs with Bluetooth and WiFi connectivity. It supports up to 10 TankMasters in the same app and shows at-a-glance levels for each tank. It’s best for RVers who want local control without relying on the Internet. It’s not ideal for remote, cloud-based monitoring since it does not support remote connectivity over the Internet.
RiVöt TankMaster RV Tank Monitor – Contactless External Sensors

This RiVöt model similarly covers fresh, gray, and black tanks with a contactless external sensor approach and a single TankMaster per tank. It’s best for travel trailers and motorhomes seeking an easy, drill-free install with a robust app experience. A potential limitation is the need for multiple TankMasters if you want to monitor several tanks independently in larger RV setups.
WiFi Solar Tank Level Monitor – Briidea

The briidea monitor emphasizes remote access via 2.4G/5G WiFi with instant app alerts and a dedicated repeater to extend range up to 330 feet. Its solar power and a 1500mAh battery enable up to six months of operation between charges in favorable light. Choose this if you need strong remote monitoring with extended range in solar-powered installations. Caution: performance may vary with extended cloudy periods, affecting battery life and connectivity.
RecPro SeeLevel RV Tank Monitoring System Panel

RecPro SeeLevel panels provide an all-in-one center for monitoring up to three tanks with an LED display. Sensor lengths vary to fit different tank shapes, and sensors can be trimmed or stacked to tailor-fit your rig. This option is best for RV owners wanting a single, easy-to-read panel without additional external displays. Limitation: installation may require careful matching of sensor lengths to your tank’s dimensions.
RecPro SeeLevel Pro RV Tank Monitoring System

This SeeLevel Pro variant reinforces the same concept with a 16-inch panel and multiple sensor lengths for flexible RV setups. It targets users who want a larger, consolidated view of tank status and easier battery monitoring alongside water level readings. Best for RVers needing a larger display and scalable sensor options. Caution: compatibility with older RV electrical systems should be checked before purchase.
Buying Guide: Key Considerations for Wireless Tank Level Monitoring
- Connectivity: Choose between Bluetooth-only, WiFi, or cellular-ready systems. Bluetooth and local WiFi are simplest for campsites without reliable internet, while WiFi-enabled systems work best with home networks or workplaces.
- Power Source: Battery-powered sensors need replacement and maintenance notes; solar-powered options provide longer runtimes but depend on sunlight exposure.
- Sensor Type: External contactless sensors are drill-free but require surface adhesion; internal sensors often need access through tank openings. Pick based on installation feasibility for your tank.
- Number of Tanks: Determine how many tanks you need to monitor and ensure the system can scale to that number without excessive cost or complexity.
- Alerting and Automation: Look for configurable thresholds, SMS/email alerts, and the ability to trigger pumps or other devices if levels drop unexpectedly.
- User Experience: A clear app interface and easy data visualization help avoid misreads and enable quick decisions in camping or rural settings.
FAQ
- What is the easiest wireless tank monitor to install on an existing RV tank?
- Do these systems require constant internet access?
- Can solar-powered monitors operate in cloudy weather?
- How many tanks can a single system monitor?
- Are external sensors reliable for long-term monitoring?
- What should I consider for RV installations?
Drill-free or external-sensor kits are typically easiest, such as certain RiVöt TankMaster models designed for contactless external installation.
No. Several options offer local Bluetooth or WiFi with data stored on a local device, while others provide cloud-based alerts if internet is available.
Solar-powered sensors work best with adequate sunlight; most include a battery and can function for several months with intermittent charging during cloudy periods.
Most systems support multiple tanks, often ranging from 1 to 3 or more, depending on the model and setup complexity.
Yes, when properly adhered and maintained, external sensors provide reliable readings without invasive installation.
Consider the number of tanks, installation style (external vs. internal), display size, and whether you need a single-panel view or multiple sensors managed through a mobile app.
