Sample pipe networks
Simple designs with short sampling pipes produce the best results. Maximum allowed
sampling pipe length is 164 feet (50 meters) in still air. In areas or applications where
the external airflow rate is greater than 3 feet per second (1 meter per second), the
maximum sampling pipe length is reduced to 33 feet (10 meters).
