Digital Air Flow Meter Cfm

A digital air flow meter, or CFM, is a device used to measure the rate of air flow in a given area. It is typically used to measure the amount of air passing through a ventilation system, such as a fan or air conditioner. The CFM is a measure of the mass of air passing through a given area in a given amount of time. The CFM is usually expressed in cubic feet per minute (CFM). It is important to note that the CFM is not a measure of the velocity of the air, but rather the mass of air passing through the area. This is why it is important to understand the difference between the CFM and the velocity of the air. The CFM is an important tool in determining the efficiency of a ventilation system, as it can help to identify areas of low air flow and areas of high air flow. Additionally, the CFM can be used to calculate the amount of air that needs to be circulated in a given area in order to maintain a comfortable temperature.
