More than 900 000 level instruments were sold all over the world by NIVELCO Process Control Co. over the last 35 years. NIVELCO is present in practically all industries with clear focuses provided by the features of the measuring technologies in its portfolio. Our intent with publishing this Application Handbook was to share a small part of our vast set of experiences with the Reader and aid our present and future clients in the selection of our instruments. When browsing this book, the Reader is to be aware of NIVELCO’s unique 5-year warranty (valid from 2018) policy which was made feasible to be introduced by the fact that our instruments are operating reliably most of the times even in extremely harsh environments in a great number of technologies of the industries we are serving. Almost no matter what level you need to measure – whether it is sewage in the USA, plastic granules in Hungary, chocolate in India or Sulphuric Acid in the Czech Republic – trust NIVELCO instruments to do the job.
