30 Years of FLEXIM mean 30 years of steady growth.

When it all began in 1990, there were four of us in a ground floor flat at the back of a typical old building in Berlin.

Today, 2020, three decades later, we have almost 500 colleagues worldwide.

30 Years of FLEXIM means 30 years of global approach.

In 1991, we sold our first clamp-on ultrasonic flowmeter. It went to a development aid project in Nepal - the roof of the world.
Our FLUXUS flowmeters are still used in development aid projects today. As the FLUXUS flowmeters measure practically everything that flows, they have long since also made their way to the industrial centres and metropolitan areas of the world.

FLUXUS is just as reliable at measuring on the smallest pipelines, such as in the paint finishing systems of the automotive industry, as on the huge pipes of hydropower plants. Building engineers from elite universities on the east coast of the US rely on FLUXUS for optimising energy efficiency just like their counterparts in Manhattan’s skyscrapers where energy flows are also measured non-invasively with FLUXUS.
