What would you do if you 2 return grills with filters in them? Measure with the grid in both? Or just at the air handler? Also does the grids fit most residential air handlers!
Good question. In a situation with multiple returns, the proper approach is to block the other smaller returns during the workflow process. The app now has a workflow selection and instructions to follow for this procedure. Also see this video covering multiple filter grilles. ua-cam.com/video/7tLwt_ZTGrs/v-deo.html
The TrueFlow will measure airflow properly as long as all of the total system airflow is moving through the grid and tolerances have been met. Tolerances: 6" clearance upstream; 2" clearance downstream; Maximum of 65 degree angle to airflow.

Will this work in package unit application?
