ARAD Woltmann Silver Turbo WSTsb Cold Water Meter

The ARAD Woltmann Silver Turbo (WSTsb) is a high-performance cold water meter designed for accuracy and durability in demanding conditions. With a wide measuring range, it ensures reliable operation at both low and high flows, while its advanced design minimises sensitivity to vibrations and humidity.

Built for longevity, the WSTsb features a replaceable measuring unit, robust bearings, and a unique magnetic coupling system. MID and WRAS-approved, it supports multiple communication options and can be installed in both horizontal and vertical orientations, handling pressures up to 16 bar and temperatures up to 60°C.

Features & benefits

  • The WSTsb has wide measuring rate that enables to serve in broaden applications and in extreme situations (low flows an high flows)
  • 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
  • Resistance – Bearings and materials used in the WSTsb have been proved to ensure long life expectancy
  • Magnetic Coupling – The WSTsb, like its predecessor, the Woltman Turbo meter – has a unique measuring unit, in which only one moving element in contact with water, and has repelling magnets installed in the impeller and the transmitting gear, instead of the attracting magnets installed in the WT
  • Compatibility – The WSTsb is also available with EV, EF, Dialog 3G, Optical Encoder (OE), Electronic Register (ER) etc.
  • Woltmann – Cold Water 60C Max
  • MID 2004/22/EC and WRAS approved
  • Horizontal and Vertical installation
  • 16 Bar max pressure
