KSR Kuebler Vietnam | Flow switches - Magnetic switches - Level Sensors

The foundation stone 50 years ago KSR Kuebler AG began to make a worldwide reputation in the field of "Level measuring technology on the Archimedes principle" (floats).

The foundation stone for the successful development of the whole KUEBLER group was laid at Zwingenberg a. Neckar in 1962 by Dipl. Ing. Heinrich Kübler. Thanks to the quick success of the then completely new type of magnetic switch, the company was able to expand beyond the borders of Germany by the early Seventies. Today, the KSR Group includes companies in Germany, France, England and China.

Since 2008 KSR-Kuebler AG is member of the WIKA group.

With approximately 350 employees, the company developes for its clients with customized engineering services - tailor-made


Today throughout the world KSR Kuebler AG is regarded as the epitome of outstanding technical performance and the highest quality, of efficiency and growth. Oil and gas, chemicals and pharmaceuticals, machinery and plant construction dominate our day-to-day business. The success of the KUEBLER group has only been possible due to the continuous development of the product range.

The first magnetic switch, which was used in lifts and automation engineering, was followed in 1965 by the magnetic float switch - a product that revolutionised the level control market. This was followed in 1974 by the development of the level sensors. Other important product developments are bypass level indicators and flow monitors.

Major focal points Today KSR Kuebler manufactures a wide range of level measuring and regulation devices for temperatures up to 4500 C or pressure ranges up to 400 bar. KSR developments are individual solutions for very different applications in chemicals and pharmaceuticals and the oil and gas sector, in ship building, machinery and plant construction, in the foodstuffs industry, water treatment and environmental engineering. The latest production techniques, uncompromising quality management and a large number of national and international approvals are prerequisites both for top quality and the good name of our company.
