The Krohne BW 25 Liquid Level Indicator operates on the displacement principle. The length of the displacement rod corresponds to the measuring range. A displacement body suspended on a measuring spring is immersed in the liquid and is subjected to an upthrust based on Archimedes’ principle, this being proportional to the mass of the liquid displaced. Every change in the weight of the rod corresponds to a certain change in the length of the spring, and is therefore an indication of the liquid level. Extension of the spring is transmitted by magnetic coupling from the measuring zone to an indicator. This transmission method permits pressure-tight separation of the measuring spring system and the scale.

About the KROHNE Group

Communication techniques are becoming ever more complex, from the field through to the control level. At the same time the demands for recording physical measured variables such as flow rates, fill levels, temperature, and pressure and analysis parameters are constantly growing. The principal requirement in this respect is absolute reliability of the measured values. This means the measuring equipment, even when subjected to disruptive influences such as changing flow profiles or inclusion of gas bubbles, must always deliver reliable values, and above all must guarantee virtually 100 % security against failure.

Measure the facts means not only reliable measurement of standard process variables – even under the most difficult process conditions – but also clear and precise process diagnostics right through to the material composition of the medium. Both of these contribute to improved process control and allow remarkable increases in process efficiency and production.

In order to guarantee this for you, more than 400 engineers in the worldwide KROHNE Group are continuously engaged in research into promising technologies for the future, in pursuit of improved measurement and further developments. We are a family-owned enterprise and we take our responsibilities seriously. We have permanent representation in more than 130 countries and employ more than 3,500 people in order to bring you highly innovative products from a single source, and tailor-made technical solutions to your measurement requirements, now and in the future.

KROHNE Group – Company History

The Start

In 1921 Ludwig Krohne began to produce variable area flow meters in Duisburg, Germany. The company moved from rented facilities to company-owned buildings in 1936. These were destroyed during the 2nd World War. As Ludwig Krohne and his son Karl both lost their lives during and in the aftermath of the war, Ludwig’s wife Anna run the company during post-war years.

Starting again

In 1949, Anna Krohne asked her 28 year old grandson Kristian Rademacher-Dubbick to join the company.
He soon took over responsibilities and 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

In 1979, Kristian Rademacher-Dubbick relinquished his position of Managing Director and became Chairman of the Board of Directors.
He could still be seen regularly in many KROHNE facilities, and he gladly followed the outstanding development of the company in the recent years.
Kristian Rademacher-Dubbick died in 2014 at the age of 92 years in Duisburg.

Present

Managed by Michael Rademacher-Dubbick (Controlling and Human Resources) and Stephan Neuburger (Sales and Marketing), KROHNE has advanced from an instrument manufacturer to a solution provider while still being an independent company owned by the Rademacher-Dubbick family.

The portfolio has been continuously expanded with complete measuring solutions and additional services to be seamlessly integrated in modern process control concepts, giving the customer as much information about the process as possible.

At the same time, new markets and industries could be won as customers to secure growth and independence from developments on single markets.
