This Level Handbook is written as a user guide for level projects in various industries. Level is a wide subject and it is impossible to cover everything in one single book, but we have aimed to include information we know users struggle with. We have also included a wide range of level applications, and even if not all are included, users should be able to find an application that is similar enough to give guidance on their own application. Please remember that choosing the appropriate level device is always up to the user, and these guidelines are recommendations based upon the experience we have gathered through the years. If you are unsure about your choice, please contact your local Emerson representative.
