Typical applications
VEGA’s level gauges accurately indicate the level of liquids or bulk
materials in vessels, reactors, or tanks.
In order to achieve a level indication over the desired length, it may be
necessary to use more than one detector. The way these multiple detectors
link together depends upon the types of detectors used. Specific details on
using multiple detectors are available from VEGA Americas, Inc.
The accuracy of quality control systems that use VEGA nuclear level
gauges is profitable to a wide range of industry operations. A number of
applications that use a level gauge are:
