Mechanical flow controller for clean liquids • Flow indication without power supply • Up to 30,000 l/h or 132.09 GPM (US) • Flange: DN15…65 / 1⁄2…21⁄2″, max. PN40 / ASME Cl 300 • -40…+300°C / -40…+570°F The DW 182 is an inline flow controller for locally indicating the flow of homogeneous clean liquids without auxiliary power. It is suitable for horizontal or vertical pipes. The flow controller comes with flanged connections (DN15…65 / 1⁄2…21⁄2″). The measuring tube and connection is made of stainless steel (1.4404 / 316 L). Two types of indicator are available: a linear scale with up to two alarm positions at the top and bottom of the indicator or a dial. The DW 182 is particularly suitable for cost-effective flow detection in various applications that don’t require high accuracy. It can deal with flows of up to 30,000 l/h or 132.09 GPM (US). There is also a high-temperature version on offer for operating conditions up to +300°C / +570°F. The DW 182 is available as non-hazardous, intrinsically safe or explosion-proof.
