Introducing Kobold’s NBK level indicators for continuous measurement, display and monitoring of liquid levels in above- or below-ground tanks.

According to the law of communicating tubes the level in the bypass tube equals the level in the vessel. The bypass tube is attached onto the side wall of the vessel. A float, with embedded circular magnets in the bypass tube follows the liquid level and transfers it, without contact, to a display fitted outside the tube or to a monitoring device. In addition, reed contacts can be installed on the bypass to evaluate limit values or to control the filling level.

Users can choose from clearly visible magnetic roller or ball displays as well as from a range of measuring transducers enabling remote transmission or level values.

Kobold NBK features:

  • Stainless steel 1.4571
  • Pressure maximum: PN320
  • Temperature maximum: 400 °C
  • Measuring maximum: 5.5 m (if longer: 2parts)
  • Electrical connection DIN flange DN15 …DN50 & ANSI-flange 1/2” … 2”

Kobold NBK finds application in tanks (shipping, storage and water) and agitator vessels.
