The SMED is a measurement unit designed for precise airflow measurement. It features dual measurement tubes, allowing simultaneous monitoring while the regulator operates. To enable accurate flow measurement even at very low air velocities in the duct, the unit is designed to produce a sufficient differential pressure, even at lower speeds.

Dimensions: 

The SMED is manufactured in standard sizes of: 100, 125, 160, 200, 250, 315, 400, 500, and 630 mm.
