Pneucleus Technologies designs and manufactures advanced instruments for gas flow measurement and control. Since 1999, we’ve specialized in mass flow controllers (MFCs), mass flow meters, and gas control systems engineered for accuracy, speed, and repeatability.

Our innovative InSitu-Sense™ sensor technology enables direct thermal mass flow measurement with response times as fast as 40 milliseconds, ensuring real-time control for critical applications. Combined with our proprietary Tri-Planar™ proportional valve, Pneucleus solutions deliver superior flow stability and drift-free performance, and long-time stability.

We serve a wide range of non-corrosive gas applications across industries such as analytical instrumentation, vacuum coating, gas mixing and gas detection & analysis. Every solution is designed for precise, reliable, and cost-effective performance.

Whether you need a thermal mass flow controller, a compact MFC for lab automation, or a high-accuracy flow meter for industrial gas systems, Pneucleus provides the technology to measure, control, and optimize gas usage with confidence.
