Type NBK
Bypass Level Indicator
- Insensitive magnetic roller or ball indicator on site without external power
- Limit switches
- Analog output
- HART, Profibus-PA, Foundation Fieldbus
Kobold bypass level indicators are used for continuous measurement, display and monitoring of liquid levels. The bypass tube is attached onto the side 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. The following indication and monitoring devices are available.
Applications
Kobold bypass level indicators are used for continuous measurement, display and monitoring of liquid levels.
