Air flow hood

Suitable for high and low flow diffusers, SwemaFlow 4001 measures both supply and exhaust air flow. The Swema measuring principle - a net of hot wires gives an accurate average value of the air flow in the flow hood opening. The design has a big cross section which minimizes the restriction of the flow. When placing the hood to an air terminal device a measurement value is instantly displayed. The flow measurement section is well defined and the flow hood features high accuracy both for supply and exhaust air.
