This measurement device is a crucial component attached to pneumatic power sources that displays the volume of air, in cubic feet per minute, that the machine delivers at a specific pressure. For instance, a reading of 5.0 at 90 PSI indicates the power source supplies 5 cubic feet of air per minute when operating at 90 pounds per square inch of pressure.
Understanding the output capabilities of a compressed air system is paramount for efficient operation. Selecting the appropriate size pneumatic power source for the tools and equipment it will power ensures optimal performance and prevents potential damage caused by insufficient air supply. Historically, imprecise methods were used to estimate airflow, leading to inefficiencies and equipment malfunctions. These devices offer a far more precise measurement.
