VEGAMAG 81
Application area
The VEGAMAG 81 magnetic level indicator consists of a bypass mounted on the side of an existing vessel. The float used in the bypass uses an integrated magnet system to transmit the liquid level contactlessly to the magnetic display mounted on the outside of the bypass. This provides an easy-to-see display of the vessel level, which can be seen from a distance.

VEGAMAG 82
Application area
The VEGAMAG 82 combines a magnetic level indicator and an additional bypass bridle chamber to combine the benefits of visual indication and process control. The VEGAMAG 82 can be configured to mount to most standard vessel process connections as well as applications where interface measurements are needed.

VEGAMAG 83
Application area
The VEGAMAG 83 is ideal for processes with low dielectric constant values, cryogenic applications, or light hydrocarbons. The VEGAMAG 83 pairs with a non-contact VEGAPULS radar instrument in the same chamber as the magnetic float. With this unique design, the radar tracks the metallic float top rather than the liquid surface.
