Depending on the type of application, the airflow meter is made as a hot-wire airflow meter, a vane airflow meter, a cup anemometer, a Pitot tube air flow meter or a pocket weather flow meter, all of which can measure air velocity as well as air pressure. Some can even detect the wind direction.

In yeast infection of the gastrointestinal tract and the perianal area, there may be itching, discomfort, and redness in the anal region.
