Magnetic Level Indicators are externally mounted chambers with visual indicators that are completely isolated from the process liquid. Inside the chamber is a magnetic float that rises and falls with the level of the liquid. When the float moves, it causes flags inside the chamber to turn and mark the level on an exterior indicator numbered roughly like a meter stick. Magnetic gauges are often used in conjunction with through-air or guided wave radar as a redundant level measurement.
Advantages of MLI include:
The VEGAMAG 61 is a standard magnetic level indicator and is designed to perform in the most demanding of applications. The wide aluminum flag design provides better visibility even in the highest temperature applications. The flag-indication used in conjunction with the scale provides a clear understanding of the process liquid levels.
The VEGAMAG 62 series combination magnetic level indicator and Bypass bridle chamber provides the benefits of both visual indication and process control by using the proven technology of the VEGAFLEX to provide the most complete visual and guided microwave radar package in the industry. The VEGAMAG 62 can be configured to mount to most standard tank process connections as well as applications where interface measurements are needed.
The VEGAMAG 63 is an integrated chamber measuring system that combines magnetic level indication with guided wave or non-contact radar measurement. This technology is used for processes with low dielectric constant values, flashing, foaming or in light hydrocarbons. It’s compact design can provide a smaller installation envelope.
The combination of VEGAPASS 81 with VEGAFLEX enables a continuous level measurement outside the vessel. The bypass consists of a standpipe which is mounted as a communicating vessel laterally to the vessel via two process fittings. This kind of mounting ensures that the level in the standpipe and the vessel are the same.
