Mopeka Pro Check Universal BLE Tank Level Sensor — Aluminum/Plastic/Poly, Bluetooth & Temp‑Compensated

The Mopeka Pro Check Universal BLE Sensor is a Bluetooth-enabled tank level monitor that accurately reads liquid levels on aluminum, plastic and poly tanks (not composite) and streams real-time data to your phone.

Designed for RVs, grills, boats and outdoor tanks, the Pro Check Universal uses Mopeka’s digital sensing technology to deliver precise level readings for propane, water, diesel, oil, butane, anhydrous and other liquids. It pairs with Mopeka’s mobile apps in North American and other non‑EU/UK markets to provide alerts, firmware updates, temperature compensation and long battery life—so you can check tank status without guesswork or unsafe handling.

How does this sensor measure levels on different tank materials?

The Pro Check measures the distance to the tank's liquid surface using a digital sensor designed to work through common tank walls such as aluminum, plastic and poly. It factors in temperature and offers calibration options so readings remain accurate across tanks of varying shapes and thicknesses.

• Works through aluminum, plastic and poly tank walls (not composite tanks)
• Built-in temperature sensing for consistent measurements
• Configurable sample timing to suit vertical or horizontal cylinders

What liquids and use cases are supported?

This model supports a wide set of liquids beyond propane—making it useful for grills, RV water systems, marine tanks and fuel storage. It is calibrated for common fuels and fluids so you can monitor propane, fresh or gray water, diesel, oil and similar commodities from your phone.

• Compatible liquids: propane, water, diesel, oil, butane, anhydrous and more
• Useful for RV freshwater/gray tanks, boat tanks, BBQ grills and backup fuel
• Not suitable for composite tank constructions

How simple is installation and ongoing use?

Installation is quick and tool-free: attach the mounting collar under the tank and secure the sensor in seconds. Once in place, the unit pairs via Bluetooth with Mopeka’s apps for live readings, customizable alerts and firmware updates—no frequent maintenance required thanks to a long-lasting battery.

• Mounting collar secures sensor beneath the tank in seconds
• Battery life up to five years under typical use
• Bluetooth connectivity for mobile readouts and adjustable alarms

What advanced features improve reading reliability?

The Pro Check Universal includes features that reduce false readings and adapt to changing conditions: a bubble level indicator to help position the sensor, firmware updates for feature improvements, and configurable sampling to match different tank orientations.

• Integrated bubble level to ensure proper mounting alignment
• Configurable sample timing and customizable alarms/alerts
• Firmware updates via the Mopeka apps to maintain accuracy

Who is this for? The Mopeka Pro Check Universal is ideal for owners who want reliable, remote tank monitoring across a variety of liquids and non-composite tanks—RV and boat owners tracking fresh or gray water, grill enthusiasts monitoring propane, and anyone storing fuel or liquids outdoors who prefers mobile alerts and hassle-free installation. Note: This unit is configured for North American and non-European/UK markets and will not function in EU/UK regions.
