Mopeka Propane Tank Sensor Pro Check — Bluetooth Magnetic, 250 Gallon Max, Ultrasonic Non‑Invasive Monitoring

The Mopeka Pro Check Bluetooth Propane Tank Sensor is a magnetic, ultrasonic gauge that wirelessly reports propane levels on your phone for tanks up to 250 gallons.

The Pro Check combines a patented ultrasonic sensing head with strong magnets and Bluetooth connectivity to deliver real-time propane level readings without any direct contact to the tank fitting. Designed for standard steel LPG cylinders and larger ASME-style tanks (up to 250 gallons), this model improves on prior Mopeka sensors with better accuracy, an integrated temperature sensor, a bubble-level indicator, configurable sampling, and longer battery life. Use it on RVs, grills, patio heaters, and storage tanks where remote monitoring saves time and prevents unexpected outages.

How does the Pro Check measure my propane without plumbing into the valve?

The Pro Check uses ultrasonic pulses to detect the liquid level inside the tank through the steel wall, so no plumbing changes or valve access are required. The device mounts with powerful magnets to the underside or side of the cylinder at the correct tank level and samples periodically to estimate fuel remaining.

• Patented ultrasonic sensor reads through steel walls for non-invasive measurement.
• Magnetic attachment secures the sensor to vertical and horizontal tanks.
• Integrated bubble-level helps position the sensor correctly for accurate readings.
• Supports larger ASME tanks up to 250 gallons (North America/non-UK model).

What connectivity and app features will I get with this gauge?

Pro Check connects to the Mopeka Tank Check app on iOS and Android via Bluetooth for direct, on-site monitoring. For remote access, add the Mopeka WiFi Bridge (sold separately) to push readings to the cloud and receive alerts from anywhere.

• Bluetooth pairing with unlimited tanks in the free Tank Check app.
• Customizable alarms and firmware updates through the app.
• Optional Mopeka WiFi Bridge for remote cloud monitoring and notifications.
• Works with Mopeka Monitor accessories to display tank status without a phone.

How durable and easy to install is the Mopeka Pro Check?

Installation takes seconds: place the sensor on the tank at the marked level and let the magnets hold it in place. The housing is built for outdoor use and the stronger battery extends time between replacements so the gauge stays active through travel and seasonal use.

• Strong magnets prevent detachment on bumpy roads or uneven terrain.
• Simple underside or side mounting—no tools required for most tanks.
• Improved battery life for prolonged monitoring without frequent changes.
• Not compatible with fiberglass tanks—designed for metal LPG cylinders.

Who is this for? The Mopeka Pro Check suits RV owners, outdoor chefs, property managers, and anyone using propane for heating or appliances who wants a reliable, non-invasive way to track fuel levels. It’s especially useful for people who manage multiple tanks and prefer app-based alerts instead of manually checking tanks. Note: this North American model is configured for non-European/UK markets and works with the Mopeka Co-Pilot and Tank Check apps only in those regions.
