In 1962, Dipl.-Ing Heinrich Kübler founded the company KSR KUEBLER in Stuttgart. Thus, the foundations for the successful history of KSR KUEBLER were laid over 50 years ago. The first magnetic switch, which was used in elevators and in automation technology, was followed in 1965 by the magnetic float switch – a product that revolutionised the level measurement market. Other major product developments in KSR KUEBLER's history are the level sensor and also the bypass level indicator.

In the early seventies, with the rapid success of the then novel magnetic switch, the company was able to expand beyond the borders of Germany. As a result, Kubler France was founded in Cernay in 1973 and Heinrich Kübler AG was founded in Switzerland in 1976.

In 1996 the company structure was converted into a public limited company: KSR KUEBLER Niveau-Messtechnik AG. At this time, KSR expanded outside the borders of Europe with the establishment of the subsidiaries KSR KUEBLER Level Control Products of America, Inc. in the USA, KSR KUEBLER Level Measurement & Control PTE LTD in Singapore and Shanghai Kuebler Automation Instrument Co. Ltd. in China. 2006 saw the acquisition of Phönix Messtechnik GmbH in Frankfurt, and in the following year the integration of Vaihinger Niveautechnik GmbH in Offenbach.

Since 2008, with its various sales subsidiaries and manufacturing facilities in France and China, KSR KUEBLER AG has been part of the WIKA Group and, with its 350 employees worldwide, develops customised solutions in the field of level measurement for its customers.
