A facilities subcontractor for Boeing recently purchased two Innova-Flo insertion vortex meters to monitor the make-up airflow rate into a painting facility. The make-up fans ensure compliance with OSHA and Boeing air quality standards, by reducing contamination and airborne particles that result from over-spray.
The Boeing standard dictates a minimum airflow of 125 FPM to the paint booths. Should the airflow drop below this level, the operation must be shut down. This type of failure could cost them millions of dollars per day in lost time and productivity.
The specifying engineer had experience with vortex meters, and chose Sierra's Innova-Flo because of its field-configuration capabilities. He stated that even though the initial cost of our equipment was somewhat higher than that of our competitors, he was convinced that he would realize significant savings by being able to reconfigure and adjust the device in the field.
Because Innova-Flo's smart electronics extend the meter's range down to a Reynold's number of 5000, they are able to measure and alarm low-velocity airflow and ensure uninterrupted painting operations.
