The DW 18 series of flow controller is ideal for locally indicating the flow of homogenous clean liquids. Adjustable switches generate alarms once switching points are reached.
The units are robust. Several variants are available to suit a wide variety of applications.
Highlights
The DW 181 inline flow controller is suitable for horizontal or vertical pipes. It can have G or NPT threaded connections, sizes ranging from ¾...2".
The measuring tube and connection are made of either bronze or 316 L (1.4404) stainless steel.
There are two types of indicator available for this variant:
DW 182 flow controller
The DW 182 inline flow controller is suitable for horizontal or vertical pipes. It has flanged connections, sizes ranging from DN 15...DN 65 or from ½...2½".
The measuring tube and connection is made of 316 L (1.4404) stainless steel. There are two types of indicator available for this variant:
For information on DW 182 flow ranges, please refer to the flow range tables.
DW 183 flow controller
The DW 183 inline flow controller is suitable for horizontal or vertical pipes. It has flanged connections , sizes ranging from DN 65...DN 200 and 2½...8".
The measuring tube and connection is made of either XC 18 (1020) carbon steel or 316 L (1.4404) stainless steel.
Carbon steel flanges with nominal diameters bigger than 100 or 4" can have 316 L stainless steel cladding. There are two types of indicator available for this variant:

DW 184 flow controller
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.
A mounting flange made of carbon steel can also have 316 L stainless steel cladding. One type of indicator is available for this variant:
