Mopeka Pro Check Universal Bluetooth Ultrasonic Tank Sensor — Fits Aluminum, Plastic & Poly Tanks up to 250 gal, Accurate Level Re

The Mopeka Pro Check Universal is a Bluetooth ultrasonic sensor that mounts under aluminum, plastic, and poly tanks to provide real‑time, accurate level readings for propane, water, diesel and other liquids.

Whether you need to know how much propane remains for a grill, monitor fresh and grey water in an RV, or check diesel and oil levels on a generator, the Mopeka Pro Check Universal is built to deliver consistent readings and long battery life. It pairs with the Mopeka Co‑Pilot and Tank Check apps (North America and non‑EU/UK markets only) and uses ultrasonic sensing plus temperature compensation to achieve high accuracy on vertical and horizontal cylinders and cylindrical poly tanks up to 250 gallons.

How accurate and reliable are the Pro Check readings?

The Pro Check Universal is engineered for precision with greater than 99% accuracy in typical applications, using ultrasonic pulses and integrated temperature sensing to adapt to varying conditions. Firmware updates and configurable sample timing improve consistency over time, while a built‑in bubble level helps ensure the sensor is mounted correctly for best results.

• Ultrasonic sensing with temperature compensation for stable measurements
• Configurable sampling intervals for faster or longer battery life
• Firmware updates via app to refine accuracy and features

Which tanks and liquids will it monitor?

The Pro Check Universal is compatible with aluminum, plastic, and poly tanks (excluding composite tanks) and supports a wide range of liquids including propane, water, diesel, oil, butane and anhydrous products. It is suitable for both vertical and horizontal cylinders and can track levels in tanks up to 250 gallons, making it versatile for grills, RVs, campers, boats, and home backup tanks.
