Heat flow, waste heat, flow in process air or flue gas

Industrial companies with energy efficiency goals are looking for more ways to achieve media savings and make them visible.

While media such as electricity, gas, water, and also compressed air have long been able to be monitored and recorded in terms of energy due to available measurement technology, a measurement solution for the media of air conditioning and process air has been missing until now. The new DIN EN ISO 50003 requires metrological proof of the energetic improvements - with the air energy meter, the use of waste heat on the air side can now finally be proven with figures, data and facts. Click into our film - it shows an air master lecture on the topic on the occasion of the Kassel Energy Manager Day.

This gap is closed by the Luftmeister "energy meter".

Based on high-temperature dynamic pressure probes, suitable temperature and humidity sensors and the highly precise flow and energy calculation in the Luftmeister, processes can be permanently monitored and energy savings can be proven. Thanks to the continuous energy flow recording (before / after), the reference value (base line) to which the savings relate is also clearly verifiable.


The following article introduces the topic of energy flow measurement in process air and illustrates it with a concrete example from the ceramics industry:


Volume flow and heat flow in flue gas - a demanding measurement task

Industrial thermal processes often emit flue gas. This is the case, for example, wherever combustion processes take place. If the flow rate is to be measured in the corresponding pipelines or vents - or even the waste heat - the corresponding parameters of the flue gas must be taken into account. If one were to assume that clean air flows in these processes, one would obtain a falsified measured value.

Luftmeister takes into account the air lambda

The Luftmeister air energy meters take into account the flue gas properties and thus provide professional measurement results. Specifically, they take into account which main flue gas components are predominant. Another innovation from Luftmeister that helps the practitioner to correctly evaluate the flow (mass flow, standard volume flow) as well as the heat flow (for waste heat considerations) and thus maximize the waste heat yield.
