Never run out of gas again.

We're excited to introduce the Electronic Multivalve 488-424 with ELG electronic level gauge, a new step forward in how LPG cylinders are monitored.

This all-in-one valve assembly combines a service valve, a pressure relief device, a quick filling automatic 80% fill-stop device, and a full capacitance electronic level gauge into a single compact unit, simplifying the system while improving safety and reliability.

What makes it stand out is the digital experience it brings to the user. A replaceable, watertight external display gives an instant PUSH-to-VIEW reading of the gas level, while integrated Bluetooth Low Energy connectivity pairs the valve with a dedicated mobile app.
From there, users can:
🔹 Monitor their gas consumption in real time
🔹 Set custom alarm levels
🔹 Receive notifications before they run low

Designed for LPG (propane/butane) applications at 30 bar and rated from -20°C to +65°C. The valve is ATEX certified, CE marked, and approved to R67-01 for safe use in demanding environments.

Whether for camping cylinders, motorhomes, or other self-filling applications, this is about giving users clear, real-time visibility over their gas supply, no more guesswork, no more running out unexpectedly.

🔧 Product spotlight: the D200, versatility built for high-purity gas

At Rotarex, our D200 is engineered around one core mission: preserving gas purity from cylinder to point of use.

Its diaphragm seal technology keeps the gas from ever contacting the valve's operating mechanism, a critical factor for maintaining mixture stability over time.

Why customers keep coming back to it:
✅ Captivated soft seat → low operating torque, no extrusion or blockage
✅ Enhanced tightness thanks to diaphragm sealing
✅ High-performance thrust pad for long-term durability
✅ 200 bar working pressure, 3.5mm or***ce, Cv = 0.35
✅ Ultra-low leak rate: 1.10⁻⁷ mbar.l/s
✅ Available in brass, stainless steel, or nickel depending on the application

Where it fits: gas calibration, laboratories, research centers and the food industry: anywhere gas purity simply isn't negotiable.

A valve that looks simple on the surface, but is engineered down to the smallest detail for reliability 💡

How much fuel is actually left in your tank?

For decades, the answer has come from a mechanical dial or from opening the tank and looking inside. Mechanical gauges lose precision exactly where it matters most: near the bottom of the tank. The result is often an empty heating oil tank in the middle of winter, and an emergency refill at a premium price.

The Electronic Level Gauge changes that for diesel, heating oil, gasoline and l**e tanks:
✅ 1% accuracy across the full range, with a continuous reading
📱 Level, consumption trends, refill prediction and low-level alerts in the Rotarex Connect app
🔧 A simple retrofit: sensor cut to size on site, no specialized tools

A shift from reacting to fuel shortages to preventing them.

We are thrilled to be featured in the gasworld Global cryogenics edition, July 2026.

This article has been a great opportunity to shine a light on what smarter level measurement really means in cryogenic applications, and how the industry is moving away from guesswork toward accurate, reliable, digital monitoring.

At the heart of it: our capacitive level gauge, designed for the most demanding liquefied gas environments. Precise. Maintenance-free. Built for the long run.

A huge thank you to Sam Cook at Chart Industries for his time and his openness in sharing real field experience with the C-Stic. Having a customer's voice in a piece like this makes all the difference.

And of course, a big thank you to the gasworld team for putting together such a great feature and giving us the space to tell this story properly.
If you haven't picked up the July edition yet, it's worth a read.

One particle can destroy a wafer worth tens of thousands of dollars.

That's not a marketing exaggeration. It's the reality of semiconductor manufacturing.

At every stage of the process (cleaning, thin-film deposition, oxidation, doping) the wafer is exposed to gases that must be absolutely pure.
Not "very pure." Absolutely pure.

Why the extreme standard?
A microscopic particle can create an irreversible defect on the circuit
A trace of moisture can compromise a deposited layer
Metallic contamination can ruin an entire production batch

The gas itself is only half the equation. The equipment carrying it, valves, regulators, fittings, has to meet that same standard, from the source all the way to the point of use. Zero particle generation. Zero compromise on tightness.

At Rotarex, that's what drives our UHP equipment design: electropolished surfaces, cleanroom assembly, individual traceability. Because in this industry, gas purity isn't a nice-to-have: it's the baseline the whole process depends on.
