„Hand me the NOLTA plug“
How an idea conquered the world



NIVA is the water technology brand of NOLTA. NIVA level controllers are the ideal solution for your applications through…


High material resistance
  • Due to special materials, even the standard versions meet the requirements of 90% of all applications.
Internal weight
  • Cost efficient since no additional cable weight is necessary. The level controller remains in place on its own weight.
Special application variants
  • Solutions for special applications such as EX zones, high temperatures, solvents, and potable water.
Easy installation
  • The same type of controller can be wired to work in filling or emptying applications.
Form follows function
  • High reliability even in small diameters. The drop shaped design keeps solid matter from getting stuck on the edges, ensuring proper function of the controller.
Reliable functionality
  • Very long lasting almost maintenance-free functionality due to robust materials and a special cast resin encapsulation technique.
