Thank you for all the suggestions.
It turned out that monitoring the fans is a simple solution.
If the fans are running, the air is flowing......

Hi all:
We are going to install a 800 MHz NMR in a pit in a small room.
Certainly oxygen sensors will be installed in the room. The sensors
and associated alarms will be activated when the oxygen level drops
below a certain level.
I am interested to know:
Is there any device for monitoring air flow (air turn over rate) in the NMR
room?
Does anybody use such kind monitor?
If the air in the NMR room is replaced with fresh air at normal turn over
rate,
the oxygen level will not drop and the oxygen sensors will not be activated.
Thanks,
