IN October 2009 Rota Yokogawa will be celebrating the first
century of being in business. The company, which since 1995
has been part of the Tokyo-based Yokogawa Group, produces
high-quality flowmeters for industrial applications including high
diameter pipes.
In 1909 the Deutsche Rotawerke was founded in Aachen,
focusing on the recently invented Rotameter. The measuring
principle of this device is based on a rotating float – hence the
name ‘Rota’. The brand name Rotameter is now often used as a
synonym for the float-based flowmeters of any manufacturer.
In 1940 production was relocated to the town of Wehr in
South Baden. In 1993 Rota introduced the first Rotamass,
a flowmeter using the Coriolis principle. The existing
co-operation with the Yokogawa Group was given a new
basis in 1995 when Rota became a subsidiary of Yokogawa
Europe BV.
Today, Rota Yokogawa is the ‘Flow Centre of Excellence’
responsible throughout the global Yokogawa Group for
measurement technologies, such as mass flow measurement
using the Coriolis principle and the Rotameter.
Just in time for the 100-year anniversary, manufacturing floor
space has been increased by 40% thanks to the inauguration of
a new production hall. The hall is one of the most modern and
innovative of its kind – and was specially designed for its flexibility:
the production facilities can be reorganised in a short space of
time, without the costly installation of new utility lines, in order to
respond rapidly to changing requirements. In the same way, the
new crane system can be very quickly adapted to new needs.
This expansion is accompanied by an increased automation
of production. The company is investing in production equipment,
robots and automated test rigs. Andreas Dobratz, managing
director of Rota Yokogawa, said: “The increase in efficiency
associated with the expansion of our production area will secure
our leading position in the field of flow measurement and pave
the way for further profitable growth.”
Over the next few years, further investment of tens of millions
of Euros is planned in buildings and plant.
Today, Rota Yokogawa develops and manufactures high-quality
flowmeters based on five measuring principles: floats, magnetic-
inductive, vortex flowmeters, Coriolis and differential head. The
best-selling products are the Coriolis flowmeters of the Rotamass 3
series developed in Wehr.
These high-tech measuring devices record the mass flow directly,
while simultaneously providing an exact measurement of volume
flow and of the density and temperature of the measured medium.
In this way, it is possible, at the same time as measuring the flow, to
also determine the concentration (eg of sugar in water). Calibrations
are carried out in the company’s own DKD-certified facility, which
also provides a calibration service to other companies.
With new products and an excellent business performance in
recent years, Rota Yokogawa says it is in good shape for the future.
The continuous development of new and existing measuring
devices will ensure that customers around the world are supplied
with top quality products ‘Made in Germany’.
