Your partner for measurement & automatation

The company ACS-CONTROL-SYSTEM GmbH was founded by Hermann Stümpfl in 1990.
Since that time ACS-CONTROL-SYSTEM GmbH is operating in the field of industrial-automation.
The technological development and the striving for innovation is the base of the activities of our company.

ACS-CONTROL-SYSTEM GmbH is being led by Marianne Stümpfl and son Joachim Stümpfl.

In 1990 the company ACS-CONTROL-SYSTEM GmbH began with the production of fill level measurement instruments. Since that time new products were developed constantly, so that we can fall back today on a large own-produced range of products. Our distribution program was extended successfully by system engineering components like controller, writer, counter, sensors and UPS-devices.

ACS-CONTROL-SYSTEM is now a medium-sized company with over 30 years experience in measurement. This experience is the basis for all our products for the measurement of level, pressure, temperature, flow and  in the field of IOT (Internet of Things).
