VFS Series

Vertical Mounting Magnetic Float Level Switches

Vertical Float Switches are established and reliable techniques in the industry for single/multiple liquid-level sensing and control in open or pressurized vessels. It offers trouble free service in conductive / non- conductive liquids under widely varying temperatures, pressures, liquid viscosity and corrosive conditions. Besides, it provides high repeatability and effects of shocks / vibrations are minimal.

Applications
  • Water / Wastewater treatment plants

  • Cooling Towers, Lubrication / filtration systems

  • Paint Shops

  • Food / Drug / Pharmaceutical / Chemical & Petrochemical Industries

  • Boilers

  • Heat Exchangers

  • Leak Detection Systems

  • Process vessels etc
