Air Flow meter Project Guidance Arduino Forum

+

· Output from sensor: 4mA20mA. Been trying to figure out how do get the flow from this sensor out to be read by my Arduino Uno. Does anyone have any idea? I need to use this flowmeter to measure the amount of air i consume daily… so i can get some info of how much of air i’m wasting at my tools at work… Please help me out…

Air Velocity Measurement | Dwyer Instruments

+

In this field, air velocity (distance traveled per unit of time) is usually expressed in feet per minute (FPM). By multiplying air velocity by the cross section area of a duct, you can determine the air volume flowing past a point in the duct per unit of time. Volume flow is usually measured in cubic feet per minute (CFM).
