Outside Airflow Measurements and Covid- Two projects (One for "right now" and one for "later")

We have had a few calls from customers lately, especially school customers who are trying to comply with outdoor air requirements to bring students back.

Here is a sample of some of the basic requirements: https://www.epa.gov/iaq-schools/epa-supports-healthy-indoor-environments-schools-during-covid-19-pandemic

One of the customers is running around with portable meters and trying get spot-measurements on outside air.

The problem with a spot measurement is that it doesn't take into consideration the varying conditions after the measurement- economizers, linkages, building pressure, occupancy changes, heating vs cooling etc.

This Ebtron airflow measurement station stays IN the ductwork for accurate and permanent monitoring: https://ebtron.com/wp-content/uploads/GTx116e-PC_Overview.pdf

The Ebtron transmitter has both analog outputs and optional data-logging, so you can verify continuously on the display or from your PC that you are meeting OSA requirements for your site.

For a quick-project: put an Ebtron airflow station on the gyms/libraries/commons/classrooms, stand-alone with data-logging to verify clean-air dilution.  You can have the station quickly and they only need 24vac power.

In the longer term: connect the stand-alone Ebtron airflow stations to the BMS for continuous monitoring and alarming.
