<strong>ARAD</strong> WATERWORKS<strong>Woltman</strong> Turbo - Water MeterModel <strong>WT</strong> IIA family of compact size <strong>Woltman</strong> watermeters with field interchangeable lightweightmeasuring units.Features• High accuracy, low loss of head and high immunityagainst abrasive media in the water due todouble magnetic coupling. This uniqueconstruction leaves only one moving element,the impeller, in contact with water. The nextmoving components, including the worm & wormwheel, are kept in a sealed, dry compartmentand have no contact with any abrasive mediapresent in the water.• Tungsten carbide impeller shaft tips & bearingsfor negligible wear in Heavy Duty use are standard.• A wide selection of sealed, magnetically coupledregisters, adaptable to 2G and 3G technologies,as well as different electrical output versions,single or multiple, are available.• Registers are: Stainless steel/glass encapsulatedand guaranteed against fogging.ApplicationsWater supply networks, agricultural applicationand industrial use.Available Sizes2” -12” (50mm - 300mm)StandardsISO 4064, AWWA, EECRegister CoverHermetically sealed register2nd magnetic couplingRight angle transmissioncompletely protectedfrom contact with water andforeign matterSealed dry chamber1st magnetic couplingTechnical SpecificationsMaximum Working PressureMaximum Liquid TemperatureBodyConnectionStandard - 16 barUpon request – 25 bar60°CCast iron, polyester coated.Optional - bronze (AWWAstdandard).es according to ISO, BS 10, AWWA or others.<strong>WT</strong> II type dialwww.arad.co.il
