KROHNE - The Innovator
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).
