Mopeka Pro Check Universal BLE Tank Sensor for Aluminium & Plastic Tanks — Temperature‑Compensated, Multi‑Year Battery

The Mopeka Pro Check Universal is a Bluetooth Low Energy tank sensor that wirelessly reports highly accurate level readings for aluminum, plastic and poly tanks to your mobile device.

Built for RVs, boats, grills and outdoor heaters, the Pro Check Universal attaches to the underside of most metal and plastic tanks to provide live level monitoring without opening valves or removing fittings. It pairs with Mopeka’s Co‑Pilot and Tank Check apps (North America and non‑EU/UK only) and combines temperature sensing, configurable sample timing, firmware updates and alarms to deliver reliable remote readouts.

How accurate and reliable are the Pro Check readings?

Pro Check uses high‑resolution sensors and signal processing to deliver extremely precise level estimates so you can plan refills and trips confidently. Readings update in real time via BLE to your phone and the device includes temperature compensation to improve consistency across conditions.

• Designed for >99% level estimation accuracy on supported tanks
• Integrated temperature sensing for improved precision
• Configurable sample timing to control update frequency
• Firmware updates maintain and improve accuracy over time

Which tanks and liquids can this sensor monitor?

The Pro Check Universal is made to work with aluminum, plastic and poly tanks—excluding composite tanks—and supports a wide variety of liquids commonly stored in portable tanks. Its calibration handles fuels and non‑fuel liquids, so the same unit can monitor propane, diesel, oil, fresh or grey water and other commodities.

• Compatible with aluminum, plastic and poly (not composite) cylinders
• Supports propane, diesel, oil, water, butane and anhydrous liquids
• Works on both vertical and horizontal tank orientations
• Not intended for composite tanks or EU/UK markets (see app compatibility)

How easy is installation and setup?

Installation is designed to be simple and secure: clamp the mounting collar beneath the tank and snap the sensor into place. After physical installation, pair the device via Bluetooth to Mopeka’s app to configure alarms, sampling intervals and firmware updates.

• Mounts to the tank underside with a quick‑attach collar for a firm hold
• No modification of the tank plumbing required
• Pairing via BLE to Co‑Pilot or Tank Check app for setup and alerts
• Customizable alarms/alerts help prevent unexpected runouts

What about battery life and durability outdoors?

Pro Check is engineered for extended field use with a multi‑year battery life and weather‑resilient construction. It’s intended for tanks that sit outdoors or in hard‑to‑reach locations where long battery life and ruggedness matter most.

• Battery life up to five years under typical use
• Weather‑resistant design for outdoor installations
• Durable mounting collar keeps the sensor steady across terrain
• Works with vertical and horizontal cylinders in harsh conditions

Who is this for: The Mopeka Pro Check Universal is ideal for RV owners, boaters, grill enthusiasts, outdoor heater users and anyone who needs dependable remote tank level monitoring for aluminum, plastic or poly cylinders. If you want smartphone alerts, long battery life and advanced sensing for a range of liquids—and you operate in North American or other non‑EU/UK regions—this sensor delivers a convenient, high‑precision solution for planning fills and avoiding surprises.
