Measurement of the amount of energy

The amount of steam used by your production machinery is often overestimated, resulting in unnecessary energy costs. At Aerni, we want to help you overcome these challenges and make your steam system more efficient. 

Where are steam quantity measurements relevant - for which planned changes?

  • The addition of new steam consuming process machinery

  • Replacement of steam boilers

  • Major changes to the steam piping system

Lack of steam volume data can lead to oversizing, resulting in increased energy consumption and additional costs.


Preventive measurements for optimally dimensioned pipelines

We offer invasive and non-invasive systems that analyse steam consumption without disturbing your existing systems. This enables the optimal dimensioning of your pipelines and saves costs.

Correct boiler size selection through to precise data

Our solutions provide precise information about the actual steam consumption, which helps you to choose the right boiler size and thus save money.

Improved efficiency through accurate measurements

We make it possible to improve steam boiler efficiency through precise measurements, which enables adjustments to the PLC system and savings in energy costs. 


• Invasive and non-invasive technology, permanent or rented

We provide various steam measurement systems. These are suitable for every application situation. Regardless of whether it is an explosion protection zone, hygiene zone, difficult to access or in tunnels. Clamp-on or permanently installed in the pipeline. We provide the right technology.

• Reference data and comparability

We have access to a database of reference data and can therefore correctly categorise the various reference steam profiles and analysis results. Based on this experience, we can determine the correct sizing and configuration of your system.

• Insights and recommendations for optimal system sizes

We share our knowledge of different technologies to improve your understanding and give you practical recommendations.

• Real-time monitoring for continuous efficiency

Our systems provide real-time monitoring with instant alerts to ensure your production is always running efficiently.
