Hot-Wire Airflow Combined with Flow Conditioning Design: Airflow Monitoring Re-evolution

In the field of air velocity and air flow monitoring, achieving stable and repeatable measurements under complex and dynamic airflow conditions has always been a technical challenge. This is especially critical in applications such as process control, cleanroom environments, and compressed air energy management, where airflow data is not just a single parameter—it serves as a fundamental input for system-wide control strategies.

Currently, two primary airflow sensing technologies are commonly used on the market: differential pressure (DP) and hot-wire (thermal) types. While DP sensors feature simple structures and offer stable measurement, they often lack sensitivity in low-velocity ranges. On the other hand, hot-wire sensors are known for their high sensitivity and fast response but can be easily affected by turbulence or installation orientation, which may lead to signal fluctuation and reduced measurement accuracy.

To address these limitations, eyc-tech has re-engineered its airflow measurement architecture with an engineering-oriented approach—integrating hot-wire sensing technology with flow conditioning structures. This solution offers improved signal stability and enhanced measurement resolution.
