NBK-16/NBK-17 Bypass Level Indicator

Brand: KOBOLD Instruments, Inc.

Kobold plastic level indicators are used for continuous measurement, display and monitoring of liquid levels. The bypass tube is attached sideways to the wall of the vessel. According to the law of communicating tubes the level in the bypass tube equals the level in the vessel.

A float with embedded circular magnets in the bypass tube follows the liquid level and transfers it in a non-contacting manner to a display fitted outside the tube or to a monitoring device.
