Flow measurement in ducts depends on a defined connection point that keeps the tubing neatly routed. AP3721 is a cylindrical duct flow port made from plastic, designed for connecting pressure tubing in duct installations.
The set includes two pieces of tube with internal Ø 4 mm and external Ø 6 mm, each 1 m long. This gives installers a ready tubing length for routing the connection between the duct port and the instrument.
