Score Breakdown
This verdict is based on the manufacturer's stated specifications, the current Amazon listing and its product images, the confirmed materials and design, real buyer ratings, and our research into the product category. Scores are consistent editorial judgments, not laboratory measurements, and we did not receive a paid sample.
Key Features
Rated greater than 99% accuracy (99.5% per the title) for real-time tank monitoring.
Built to meet the outdoor demands of RVs, grills and outdoor heaters.
An included collar secures to the tank underside in seconds.
Supports propane, water, oil, diesel, butane, anhydrous and other liquid commodities.
Adds integrated temperature readings and a tank level indicator.
Works seamlessly with either cylinder orientation.
Design and Build Quality
The sensor mounts to the underside of a tank using an included mounting collar secured to nonmagnetic surfaces, installed in seconds according to the listing. It integrates temperature sensing and a tank bubble level indicator, with configurable sample timing, firmware updates, and customizable alarms and alerts.
It works with both vertical and horizontal cylinders and is rated for up to five years of battery life, built to withstand harsh outdoor elements on tanks that are outdoors or hard to reach.
Performance in Everyday Use
Accuracy performance is rated by the listing at greater than 99%, with the product title specifying 99.5%, giving real-time tank level readings on a mobile device rather than requiring a manual check. Battery performance is rated up to five years, reducing how often the sensor needs attention.
Compatibility performance covers tanks holding propane, water, oil, diesel, butane, anhydrous and other liquid commodities, but explicitly excludes composite tanks and black water tanks, for which the listing recommends a different top-down Mopeka sensor such as the Pro 200 or TD range.
How It Performs: The Evidence
| Decision factor | What we found | Evidence and measurement | Score | Why it matters |
|---|---|---|---|---|
| Accuracy | Greater than 99% (99.5% per title) | Title states 99.5% Accuracy and listing states gives users the ability to monitor tank levels with >99% accuracy in real-time | 8.4 | A specific accuracy percentage gives a measurable basis for the monitoring claim |
| Battery life | Up to five years | Listing states Mopeka's Pro Check has a battery life of up to five years | 8.3 | A specific battery lifespan figure supports the long-term, low-maintenance claim |
| Installation | Mounting collar secures in seconds | Listing states the tank sensor easily attaches to the underside of your tank by mounting the collar and can be secured in seconds | 8.2 | A described quick mounting process supports the effortless-installation claim |
| Tank material compatibility | Aluminum, plastic and poly tanks (not composite) | Listing states check the levels on your aluminum, plastic, and poly tanks (except for composite tanks) | 7.9 | Naming the specific supported and excluded tank materials avoids a mismatched purchase |
| Liquid compatibility | Propane, water, oil, diesel, butane, anhydrous and more | Listing states the sensor supports tanks that hold diesel, oil, water, butane, anhydrous and other liquid commodities | 7.8 | Naming the specific supported liquids confirms the sensor's broad monitoring use case |
| App connectivity | Bluetooth with Co-Pilot and Tank Check apps | Listing states the Mopeka Co-Pilot App and Tank Check App are compatible only with this model in North American and non-European/UK markets | 8.0 | Confirming the specific compatible apps and market scope avoids buying a sensor that won't work with the user's region |
