To ensure a lasting function, the sensor must be made of the right materials, usually expensive alloys, and equipped with special elastomer seals. When installing or de-installing a sensor, the workforce has to wear extensive protective equipment. In addition, the surrounding area must be closed off during such a procedure. These measures are necessary and involve high costs. They also pose a security risk.
The stored chemicals, especially those that are highly acidic or alkaline, are usually highly toxic, corrosive substances that can leave residues and easily outgas. Any contact with or release of such substances into the atmosphere can quickly become dangerous for personnel. At the Belvedere plant, these chemical substances are carefully monitored. Accurate level measurement helps avoid overfilling and ensures that there are enough raw materials for the process.
