Air/Gas Flow Measurement For Turbomachinery: What You Don't Know Can Be Frustrating

By Art Womack

The accurate, repeatable flow measurement of air and gases is critical to the safe, efficient and cost-effective operation of turbomachinery and related equipment in the electric power generation, oil/gas production/refining and other industries. Choosing the wrong air/gas flow meter sensing technology can have significant consequences.

There are at least nine common industrial flow measurement technologies available today, all having their strengths and weaknesses depending on the specific application, operating environment, maintenance, cost and other factors. Understanding these flow sensing technologies prevents mistakes that can be costly or even dangerous depending on the application. The costs associated with installing the wrong flow meter in terms of extra maintenance, repairs and spares in larger operations can add up quickly.
