AETOS Mass Flow Meter
Precise gas flow measurement. Ready to go right away.
The flexible mass flow meter for precise, fast, and reliable measurement of gas flow
The AETOS is available as a mass flow meter or, with valves, as a mass flow controller. It operates on the laminar flow principle, in which the measured differential pressure is directly proportional to the flow rate. The measured pressure signal is much faster than thermal evaluation and can therefore not only provide rapid measurements but also very fast temperature compensation. As a result, deviations caused by changing process or environmental conditions are no longer an issue for control systems.
The TrigasDM AETOS measures gas flow rates precisely – without a warm-up time, without inlet and outlet straight sections, and regardless of the installation orientation. This flexibility makes it easy to integrate the mass flow meter into existing systems and compact test setups.
With fast response times, a turndown ratio of up to 2000:1, and a convenient USB-C connection, the AETOS is the high-performance solution for industry, research, test benches, and dynamic applications.
Developed and manufactured in Germany/Europe – for demanding measurement and control applications.
AETOS mass flow meters are high-performance devices equipped with high-quality sensors that ensure highly accurate and repeatable measurements in your application. They are identical in design to the AETOS mass flow controllers for gases and feature the same operating concept.
For OEM applications and large-volume orders, we tailor the devices to include only the functions you need, so we can provide you with exactly the device you require at an attractive price.

AETOS – Your Advantages at a Glance
One Device. One Point of Contact. Reliable Measurement Results.
Thanks to our close cooperation with TrigasFI, a DAkkS-accredited specialist laboratory for gas and liquid flow measurements, you benefit from AETOS devices and the corresponding calibration services – all from a single source.
Made in Germany – Engineered for Excellence
The AETOS is entirely developed and manufactured in Germany. This allows us to combine German engineering excellence with short decision-making processes, rigorous quality control and consistently high manufacturing standards.
Multi-Gas – without Recalibration
Change Gases via Software –instantly and flexible. Choose from a wide range of available gases via software, without the need for individual real-gas calibration for each application. Calibrate once and benefit from consistently high measurement accuracy across all supported gases.
Easy PC Connection via USB
The TrigasDM AETOS can be easily integrated into existing systems and connected via various interfaces. A particular highlight is the USB-C interface, which ensures convenient connectivity and straightforward configuration.
Accurate Measurements Regardless of Installation Orientation
The AETOS operates reliably and accurately in any installation orientation. Install it wherever it best suits your application! No inlet or outlet straight pipe sections are required, and the AETOS can even be installed directly downstream of a 90° bend..
Instantly Ready – No Warm-Up Required
While thermal MFCs typically require a warm-up period of 5–30 minutes, the AETOS delivers precise and stable measurements immediately after switch-on – with no waiting time required.
Impressive Measurement Range
With a true 2000:1 turndown ratio, the AETOS covers a wide range of flow rates while maintaining excellent measurement accuracy – making it ideal for applications with highly variable flow rates.
Maximum Dynamics – Millisecond Response Times
Whether for fast control loops or dynamic process sequences, the AETOS responds extremely quickly and delivers real-time measurement data.
Personal Support. Direct Contact. No Call Queues.
When it matters most, you speak directly with people who understand your product and your application. Our German-speaking sales and service team provides personal, reliable support with fast response times – from your initial enquiry to finding the right solution.
Applications – The AETOS in Action
Whether used for nitrogen atomisation in automotive paint processes, precise burner control in glass fibre production or leak monitoring in gas networks – the AETOS handles even the most demanding measurement and control tasks with ease.
Wide Measurement Range. Maximum Flexibility. Real-Time Data..
The AETOS offers an impressive 2000:1 turndown ratio, delivering precise measurements across a wide range of flow rates, from very low to high flows.
With a wide selection of available gases, you can adapt flexibly to different applications without the need for recalibration. Thanks to versatile interfaces such as analogue outputs and USB-C, the AETOS provides real-time data on flow, temperature and pressure.
One Device. Multiple Applications.
New Test Conditions? No Need for a New Flow Meter.
For laboratory setups and development projects, the AETOS provides a flexible solution for a wide range of measurement tasks. When gas types, flow ranges or test conditions change, the device configuration can be adapted to meet the specific requirements of each application.
For Precise and Reliable Monitoring of Gas Processes
For process and development applications where reproducible gas flows and a traceable measurement chain are essential..
For Controlled Gas Flows in Vacuum Chambers and Coating Systems
In sputtering and other coating processes, controlled and reproducible gas supply is essential. The AETOS enables precise monitoring and control of gas flows and can be flexibly integrated even in demanding installation environments.
For Flexible Integration into Existing and New Systems
Ideal for dynamic test sequences, test benches and automated testing systems. Fast response times and direct PC connectivity simplify integration into existing test bench software.
Flexible Gas Measurement Technology for Stable Industrial Processes
In industrial gas processes, stable measurement results, reliable system integration and application-specific device configurations are essential. The AETOS supports measurement and control tasks involving varying flow rates and the use of different gases.
