Anemometer to Measure Flotation Cell Air Flow - Self ...

Jul 05, 2017 · Measuring the air flow with an Anemometer gave me a relative idea of cell blockage which affected air supply and therefore recovery. There is nothing scientific about the method/technique I used. I just bought a $25 Anemometer on Amazon and held it just at the air-inlet to get a reading. I built some kind of model to estimate the airflow impact.

What Is An Anemometer And What Does It Measure?

Aug 28, 2018 · An anemometer is an instrument used to measure the speed or velocity of gases either in a contained flow, such as airflow in a duct, or in unconfined flows, such as atmospheric wind. To determine the velocity, an anemometer detects change in some physical property of the fluid or the effect of the fluid on a mechanical device inserted into the flow.

Make Mass Flow Rate Measurements with an Anemometer

To maintain accuracy when using the anemometer to measure air speed in a duct, we recommend calibrating the anemometer for the specific application.
