Mechanical flow monitor DW 184 Mechanical flow controller for clean liquids* Flow indication without power supply * For applications with large pipes of any size * Flange: ≥DN150 /6", max. PN40 / ASME Cl 300 * -40…+300°C / -40…+570°F The DW 184 is an insertion-type flow controller for checking the flow velocity of liquids without auxiliary power. It is suitable for horizontal and vertical pipes ≥DN250 / 10″. The device comes with DN150 (PN16/40) or 6” (ASME Cl 150/300) flanges. The internals are made of stainless steel (1.4404 / 316 L). The indicator is available with a linear scale with alarm positions at the top and bottom. The DW 184 is particularly suitable for cost-effective flow detection in various applications that don't require high accuracy. It can deal with flow velocities up to 4 m/s or 13.1 ft/s. A high-temperature version can be provided for operating conditions up to +300°C / +570°F. The mechanical flow controller is available as non-hazardous, intrinsically-safe or explosion-proof version. Product highlights * Cost-effective insertion-type device * Housing removable under process conditions * Permanent readings in any position * With dial or linear scale with up to two alarm positions * High reliability and repeatability (±3% of switching point) * Wide range of wetted parts materials * With optional stainless steel housing * Individually calibrated and tested * Installation independent of pipe diameter Typical applications General * Cost-effective flow detection * Cooling systems * Pump protection * Lubrication control * Cavitation alarm
