Our Story (copy from Rittmeyer site at www.rittmeyer.com)​

1904
Franz Rittmeyer (born in 1875) starts building remote water level indicators in Appenzell.

1905
Franz Rittmeyer moves from Appenzell to Thalwil where the road infrastructure is better and access to his customers easier.

1919
Franz Rittmeyer moves to Baar where he purchases the house „Zum Grenzstein“ (Landmark) and surrounding property which still accommodates the company’s main office to this day. The property is later expanded. The structures are enlarged in 5 stages between 1933 and 1960.

1931
The reference list shows 477 completed installations.

1932
The economic crisis originating in the United States reaches Switzerland. Despite the difficult circumstances, the company does not have to lay off employees, thus demonstrating that the production program is not affected by economic depressions.

1939
Begin of World War II. Business during the war is satisfactory. This rather peaceful area of operation is hardly affected by the devastating war.

The first pressure compensator with Bourdon tube is presented at the Swiss National Exhibition.

1945
The years following the war bring an unexpected boost and dynamic growth for the company with respect to personnel and construction.

The difficult transition from a workshop to a state-of-the-art industrial enterprise with its tremendous organizational issues is accomplished.

1951
Robert Rittmeyer joins the company management.

1962
Start of electronic developments

1965
Sound frequency transmission system

1965-1969
New devices are being developed with improved construction and production methods. Funding for research and development is made available, particularly for waste water removal and electronics, in due consideration of the same high standards the company has applied to quality, reliability and durability as a guiding principle since its formation.
The company accepts commissions to design, deliver and install integral communications and control systems in Switzerland and abroad and operates as the leading project coordinator.

1971-1972
Construction of the new production facility (approx. 2800 m2).

Production and assembly facilities as well as inspection, logistics and warehousing are consolidated.

1972
The electro-magnetic controller to transmit a digital, absolute measured value is introduced.

1974
With Dr. Seiler, Kabelwerke Brugg joins the Administrative Board.

The structural engineering standards are more or less completed. This technology allows for much more rational work methods in equipment engineering. At the same time, a fundamental structural change from electro-magnetic to electronic solutions is emerging leading to more procurement and less in-house production.

1976
The CAI process system is implemented as a logging and control system. Rittmeyer ventures into computer technology for water management.

The first subsidiary in Germany is established: Rittmeyer GmbH Stuttgart (established in Ohmden).

1977
The subsidiary in Austria (Vienna) is established.

The gravity-controlled angle transmitter RIVERT is being developed.

1978
The RIDAT 1 telecontrol system with a SC/MP microprocessor is introduced on the market.

1979
The RIFLEX ultrasound flow meter is being developed.
Kabelwerke Brugg acquires the majority of shares.
