Application
A major supplier to the food industry in Asia has specialized in the production of enzymes. These are used, among other places, in the brewing industry, in starch processing and in cheese production. The hygienic requirements for the process technology are very high. The process water lines are therefore cleaned regularly through active chlorination. The active ingredient sodium hypochlorite, which is stored in plastic PE tanks outdoors and metered in for the cleaning process, has proven its worth here. Until now, the level in the tank was displayed with a gauge glass. This meant regular on-site checks and an elaborate inventory management system. The medium is also very reactive with many substances, particularly organic materials. So a search was made for a simple, reliable and economical measurement solution – if possible, one not requiring invasive changes to the container.

VEGAPULS 61
The solution
The ideal solution is the radar sensor VEGAPULS 61, which measures the level contactlessly through the closed vessel top. It is mounted with its mounting bracket on a boom above the storage tank. Changes to the container, such as the installation of a mounting socket with through-hole, are thus not necessary.
The measurement is reliable regardless of rain, sun and wind. Thanks to two-wire technology, the output signal can be integrated directly into the control system.
For the user, this solution means dependable production, efficient cleaning and time savings resulting from the discontinuation of manual reading and gauge maintenance.
User benefits
- Fully automatic cleaning, thus high production security
- Economical operation of the disinfection system thanks to precise measurement data
- Convenient mounting of the sensor without creating an opening in the vessel
- Time savings, since regular manual reading and maintenance no longer required
