3 DescriptionThe ample space around the core of the in-line helical axial turbine allows foreign matter to pass through the meter without 4064, EEC DimensionsIrrigation & Agriculture Water Meter - Model WMR Performance dataHead Loss CurveInstallation Requirements The Water meter may be installed in any position. For non-horizontal position the flow shall be upwards. The meter shall be full of Water while operating. Prior to installation of a meter the pipeline shall be thoroughly flushed. Straight pipe section of the same diameter D as the meter, having lengths of 10D and 5D shall be installed upstream and downstream of the meter TurboWater Meter - Model WT II Features High accuracy, low loss of head and high immunity against abrasive media in the Water due to double magnetic coupling.

4 This unique construction leaves only one moving element, the impeller, in contact with Water . The next moving components, including the worm & worm wheel, are kept in a sealed, dry compartment and have no contact with any abrasive media present in the Water . Tungsten carbide impeller shaft tips & bearings for negligible wear in Heavy Duty use are standard. A wide selection of sealed, magnetically coupled registers, adaptable to G and 3G technologies, as well as different electrical output versions, single or multiple, are available.

5 Registers are: Stainless steel/glass encapsulated and guaranteed against family of compact size Woltman Water Meters with field interchangeable lightweight measuring Sizes2 -12 (50mm - 300mm)Technical SpecificationsMaximum Working PressureStandard - 16 bar Upon request 25 barMaximum Liquid Temperature60 CBodyCast iron, polyester coated.

6 For non-horizontal positions the flow shall be upwards. The meter shall be full of Water while operating. Prior to installation of a meter, the pipeline shall be thoroughly flushed. Straight pipe section of the same diameter D as the meter, having length of 5D and D shall be installed upstream and downstream of the meter Limit9 Woltman Silver TurboWater Meter - Model WST SB FeaturesIn addition to the features offered by Arad s traditional Woltman Turbine meter, the Woltman Silver Turbo (WST) offers the following: Accuracy The WST s accuracy curve is the widest known in the market: The minimum flow rate is 35%-5 % below the ISO standard for such Meters and the maximum flow rate is 150%- 33% above it.

7 The combination of these unique features allows the use of the WST in broader applications and in extreme situations. High accuracy at very low flow rate assures minimize losses of unmeasured Water (R-1 0) Wide measuring rate - possible to measure very high flow rate No sensitivity to working conditions like vibrations No sensitivity to humidity conditions (even if dry chamber is full of Water ) The worm assy. is in a separate kit, which enable easy replacement if necessary Easy assembly process Resistance Bearings and materials used in the WST have been proved to ensure durability far beyond the ISO Standard requirement.

8 This feature ensures that the meter can function in extreme conditions where other Meters fail to maintain a sufficient level of life expectancy than similar Meters in the market Magnetic Coupling The WST, like its predecessor, the Woltman Turbo meter - has a unique measuring unit, in which only one moving element, the impeller, is in contact with the Water . The other moving components, including the worm & transmission gear, are kept sealed inside a dry compartment and have no contact with any of the abrasive elements present in the Water . WST has repelling magnets installed in the impeller and the transmitting gear, instead of the attracting magnets installed in the WT Compatibility The WST is also available with EV, EF, Dialog G, Dialog 3G, MPE, DPE etc.

9 The WST s measuring unit can be installed in any of the existing Arad WT new Woltman Silver Turbo WST is the latest state of the art meter developed by ARAD s R&D methods and technologies were implemented in order to present a product much superior to those found in the market Sizes2 - 8 (50mm - 200mm)Technical SpecificationsMaximum Working PressureStandard - 16 bar Upon request 25 barMaximum Liquid Temperature60 CBodyCast iron, polyester coated.
