The Start: In  1921   LUDWIG KROHNE began to produce variable area flowmeters. The  company moved   from rented facilities to company-owned buildings in  1936. These were   destroyed during the 2nd World War. 
Starting again: In 1949 Ludwig KROHNE’s grandson,  Kristian Dubbick   joined the company. Under his leadership KROHNE –  with an initial workforce   of only 8 people - grew to become a leading  and one of the most innovative   companies for flow measuring devices. 
The Generation Change: At the end of the 1970’s  Kristian Dubbick   relinquished his position of Managing Director and  became Chairman of the   Board of Directors. Today the company is  managed by Michael Dubbick   (Controlling and Human  Resources) and Stephan Neuburger (Sales and   Marketing).
