In the world of flow measurement different techniques are used. A well-known technique is thermal mass flow measurement. Thermal mass flow meters and controllers can be divided into 3 different sensor principles:
- Bypass principle
- Inline principle for gases (CTA)
- Inline principle for liquids (CTA/CPA)
In this blog I would like to share my insights on the
inline principle for gases, also known as CTA or ‘
Constant Temperature Anemometry’ or
direct through-flow measurement.
Let me start by explaining this technique followed by my top 5 reasons why to use flow meters using this principle.
