Dear all,

I have been going around in circles with this requirement for a time now and I am not very sure which time of device is generally installed for airflow monitoring. I was wondering if anyone here could provide some examples of acceptable devices for a VAV system.

As far as I am concerned the device should be something like this: https://www.bapihvac.com/application_note/determining-duct-air-flow-in-c...

Could anybody confirm, please.

Thanks
