Measure Air Velocity With Precision Using Professional Flow Meters!

Calculating average flow rates through ducts, pipes, hoods and stacks is simple. The cross-sectional area of the duct is multiplied by the average air velocity to find the volume per time or flow rate. On the other hand, gathering data accurately and precisely to measure air velocity across ducts, has been more difficult due to differing degrees of friction across a duct.

Poor data collection produces the errors in duct balancing. The challenge is; “How to acquire the average flow rate measurement across differing cross-sections of duct – and how can using professional flow meters help?”
