LPG Multivalve 488 - 424 with ELG electronic level gauge for self-filling cylinders

The LPG multi-valve is a compact all-in-one valve assembly that combines multiple essential functions into a single device. It integrates a service valve, a fillstop, a safety relief valve and a level indicator into a single unit. It is designed for use on refillable cylinders for motorhomes.

The multivalve is equipped with a sensor that digitally measures the liquid level inside your cylinder with the highest precision through continuous monitoring. Once connected to our digital measurement technology, the measured data can be transmitted directly to a smartphone, allowing users to access accurate level information in real time and manage refills more efficiently.

What is an LPG multivalve?

The Rotarex SRG multivalve is an integrated valve system designed for refillable propane cylinders used in automotive and vehicle applications, including vans and motorhomes. It combines several essential functions in one compact assembly, such as filling, gas withdrawal, safety management and level indication.

This type of all-in-one solution is particularly well suited for modern gas systems, where space, efficiency and reliability are critical. For self-filling cylinders, it ensures safer and more controlled refilling while simplifying the overall cylinder design.

The multivalve system enables a more compact, cleaner and easier-to-integrate architecture, making it ideal for use in a wide range of vehicle systems. It also supports the integration of compatible accessories and monitoring solutions, providing more flexibility and additional details for advanced system configurations.

What safety features do LPG multivalves have?

LPG multivalves are designed to enhance safety by integrating several critical protection and control functions into a single compact component. They include a pressure relief function that protects the cylinder against overpressure by safely releasing gas in a controlled manner when needed, as well as effective filling control, particularly thanks to the 80% fillstop, which automatically limits the filling level and leaves sufficient space for gas expansion. In addition, the integrated shut-off valve allows the user to safely control or stop the gas flow when required, while the level indication provides visibility on the remaining gas, helping to prevent unexpected run-outs and improve overall system management. By combining these features into one all-in-one system, LPG multivalves reduce the number of connections and potential leak points, improving overall safety and reliability.

What are the avdantages of the electronic level indicator?

The electronic level indicator offers a more intuitive and user-friendly way to monitor the remaining LPG level compared to traditional mechanical solutions. Thanks to digital measurement, users benefit from a clearer and more precise reading, making it easier to understand the actual gas content at a glance.

The system is designed for easy installation and seamless integration with your LPG setup. It can be paired with an external display connected to the valve, allowing you to check the gas level without needing to read it directly on the cylinder. This display is equipped with a longer cable and can be mounted on any flat surface, improving accessibility and visibility.

The level is displayed from 0 to 100%, providing a simple and accurate indication of the remaining gas. In addition, the device can be connected to our mobile application via Bluetooth, enabling convenient remote monitoring and enhancing the overall user experience.

Monitor Your LPG Anytime with Rotarex Connect

By connecting your digital LPG level gauge to Rotarex Connect, you can monitor the remaining gas level in your cylinder or propane tank directly from your smartphone in real time. As part of an advanced remote monitoring solution, the system uses an integrated high-precision capacitive sensor to deliver continuous and highly accurate measurements (up to ±1% over the full scale) far exceeding the capabilities of traditional mechanical gauges.

This level of precision allows you to track your LPG consumption with confidence, anticipate refills more effectively and avoid unexpected shortages. Whether for home, leisure or light commercial applications, you always have a clear and reliable view of your remaining gas.

For added convenience, customizable level alert can be set within the app. When the gas level reaches a predefined threshold, you receive an automatic notification, giving you time to plan your next refill and ensuring uninterrupted supply.

With real-time monitoring, smart alerts and advanced accuracy, Rotarex Connect offers a simple, reliable and fully controlled LPG management experience. Contact us to learn more about the advantages of Rotarex Connect.

FAQ about LPG multivalve for camping car

What is an LPG multivalve?

An LPG multivalve is an integrated valve system designed for refillable LPG cylinders used in motorhomes and leisure vehicles. It combines several essential functions into one compact unit, including shut off valve, gas filling, safety features and level indication. This all-in-one design simplifies the cylinder system while improving safety and ease of use.

What are the benefits of using a multivalve?

Using a multivalve provides a safer, more compact and more efficient solution compared to using separate components. It enables controlled filling (particularly with the 80% fill stop) integrates key safety functions such as pressure relief and shut-off, and reduces the number of connections, which helps minimize potential leak points. It also simplifies installation and improves overall system reliability in motorhome applications.

What is an ELG electronic level gauge?

An ELG (Electronic Level Gauge) is a digital system that measures the LPG level inside the cylinder. Unlike traditional mechanical gauges, it uses an electronic sensor to provide continuous and more accurate level information. When connected to a monitoring system, it can transmit data to an external display or smartphone for easier access and better visibility.

What are the advantages of digital level measurement?

Digital level measurement provides a clearer, more precise and more intuitive reading of the remaining gas level. It allows users to monitor their LPG consumption more accurately, anticipate refilling needs and avoid unexpected shortages. With features such as real-time monitoring, external displays and smartphone connectivity, it also offers a more modern and convenient user experience.
