I'm not aware of any. At some campuses, I have monitored the "face" velocity annually to try to detect a system failure before such failures were detected due to odor or other problems. Other campuses I have worked on have too many of these to try to maintain this approach.
These devices only have a capture zone of a few inches, so the best practice is to get the snorkel as close to the source as possible to get as much capture as possible.
