The DW 184 insertion-type flow controller checks flow velocity. It is suitable for horizontal and vertical pipes with nominal diameters of 250 mm / 10" or bigger - there is no maximum pipe diameter.

It is installed on a DN 150 PN 16/40 or 6" ASME150/300 lbs mounting flange. The measuring tube and connection is made of either 1020 (XC 18) carbon steel or 316 L (1.4404) stainless steel.
