Advanced Ultrasonic LPG Level Monitoring

Precision Gas Measurement for Caravans, RVs, and Industrial Applications

Running out of LPG during an off-grid trip or crucial commercial operation is a frustrating and entirely preventable problem. Traditional pressure gauges often provide delayed or inaccurate readings, leaving users uncertain about their actual gas reserves. The Mopeka Pro Check offers a highly technical solution to this issue by utilising advanced ultrasonic sensing to measure the exact fluid level inside your gas bottle, ensuring you are never caught without fuel.

How the Mopeka Pro Check Works

Unlike basic mechanical dials that estimate volume based on pressure, this Mopeka gas sensor uses ultrasonic technology to detect the precise level of liquid propane or butane. By sending sound waves through the base of the cylinder, the sensor accurately calculates the remaining volume and instantly relays this data. This eliminates the inherent unreliability of standard gauges and provides a dependable reading regardless of external temperature fluctuations.

Seamless Bluetooth Connectivity and System Integration

This bluetooth gas bottle level indicator connects directly to your smartphone or tablet via the free Mopeka Check application. The interface provides real-time updates and low-level alerts directly to your device. For comprehensive off-grid power systems, the sensor features native compatibility with Victron GX devices, such as the Cerbo GX. This allows for centralised monitoring of both your electrical and gas reserves on a single digital dashboard.

Versatile Tank Compatibility and Installation

Engineered for flexibility, the Mopeka Pro Check mounts securely to the bottom of the tank using built-in, heavy-duty magnets. It is suitable for both horizontal and vertical cylinders. For Australian users, the package includes dedicated cylinder spacers, ensuring adequate ground clearance for the sensor when fitted to standard 4kg and 9kg LPG cylinders. The unit is also highly scalable, capable of monitoring large residential or commercial storage tanks up to 1000 gallons (approx. 3785 L).

Key Features of the Mopeka Pro Check

• Highly accurate ultrasonic sensor technology for real-time volume readings.
• Direct Bluetooth communication to mobile devices for instant gas level monitoring.
• Native compatibility with Victron GX systems for integrated off-grid management.
• Fast magnetic mounting system allowing for installation in under 60 seconds.
• Includes dedicated tank spacers to suit standard Australian 4kg and 9kg gas bottles.
• Powered by a user-replaceable CR2032 coin battery providing up to two to three years of continuous operation.
• Broad compatibility with steel and aluminium tanks, ranging from small portable bottles to bulk storage up to 3785 L.

Eliminate the Guesswork of Gas Management

Relying on outdated mechanical monitors or the manual "hot water test" fails to provide the accuracy needed for reliable off-grid living. By upgrading to a dedicated LPG level sensor, you significantly reduce the risk of unexpected gas depletion. This protects critical systems like gas-powered refrigerators from shutting down and ensures continuous operation of heating appliances during cold weather.

Installation Instructions

Setup is straightforward and non-invasive. Simply clean the exterior base of your tank, apply a small amount of the provided sonic grease to the sensor pad, attach the unit magnetically, and sync it with your chosen monitoring device. For full visual instructions and troubleshooting, please refer to the Mopeka Pro Check Instructions.
