TSI University Training: Taking Measurements with TSI VelociCalc 9565 Air Velocity Meters

TSI VelociCalc® 9565 Ventilation Meter: Calculating Percentage of Outside Air

This short video demonstration explains how to make a percent outside air calculation using a TSI ventilation meter. This calculation, based on measurements of return air, supply air, and outside air, helps determine if enough outside air is supplied in a particular building or space.

TSI VelociCalc® 9565 Ventilation Meter: Setup for a Duct Traverse

This short video shows you how to set up a TSI air velocity meter to perform a duct traverse with a datalogging device. It covers the advanced datalogging features in the TSI 9565 for taking all necessary measurements for a true duct traverse study.

TSI VelociCalc® 9565 Ventilation Meter: Performing a Duct Traverse

This short video shows you how to perform a duct traverse using both a pitot probe and a hot wire probe to get an accurate idea of the average flow rate within a specific section of ductwork.
