Manufacturing/production processes are housed in structures with sophisticated mechanical systems, designed to operate in support of the specific environmental requirements of the process, including cleanliness. They include many types of operations and industries. An example of one such facility is an assembly of multiple buildings with different types of labs, which incorporates more than 350 EBTRON air flow measuring stations in continuous service since commissioning in 2003. It also includes any process where clean intake/combustion air needs to be monitored or metered. The majority of these applications tend to fall within the general description. There are many more applications.
