Water Meter ITRON WOLTEX 500 mm

Water Meter ITRON WOLTEX               Horizontal Woltmann meter with extended   Ease of Installation, Read and       accuracy range for water distribution applications Maintenance                                 Woltex is a horizontal helix Woltmann meter,   Woltex range is available in various lengths and   available in sizes from DN 50 to 500.     connections to minimize installation costs.                 Interchangeable approved mechanisms allows   Extended Approved Range       easy maintenance without re-calibration.     Woltex is approved with normal flow range as per Ease of read in the toughest environments (ie:   ISO 4064-1:1993, as class B and also, with   flooded pits) is secured by orientable hermetically   superior permanent flow-rate. It means that one sealed register (copper can/ mineral glass     size (DN) has 2 different flow range :     envelope).         - N for Normal Permanent Flow Rate;                 - G for Greater Permanent Flow Rate;     Communication Device       Greater version is special for metering points   Pre-equipped for future communication     where peak flows are recurrent.     through Cyble.                                 Endurance & Peak Flow                   Resistance                     This extended approval is the result of more than             twenty years experience in Horizontal Woltmann             design, from the first hydrodynamically balanced             helix patent in 1985 still resulting in unmatched             endurance capabilities to the use of high quality             materials.                                                                       Metrological Characteristics                   Typical Performance                   Nominal diameter (DN)    : 20" (500 mm)           Starting flowrate     : 20 m3/h             Accuracy ± 2% from*   : 40 m3/h             Accuracy ± 5% from*   : 30 m3/h             Admissible peak flow (10’ max) : 7000 m3/h           Max. admissible flowrate (continuous) : 5000 m3/h           Head loss at Qmax     : 0.3 bar             Max. admissible temperature   : 50 °C             Max. admissible pressure   : 20 bar             Min. scale interval     : 20 L             Indicating range     : 99999999 m3           Cyble HF pulse weight   : 1000 L
