Our core competencies

Motivation
Our customers make the highest of demands on the quality of our measuring instruments. Rightly so, because the precision of our products ensures their commercial success. This motivates us afresh each day, employees and management alike. This is how we profitably bring our decades of experience in the field of flow measurement technology to bear on a daily basis. Our technical expertise has been repeatedly attested to by external institutions. All of this enables us to approach each new challenge with confidence.

Expertise
As a manufacturer of pressure bearing components, we can demonstrate various competencies in pressure equipment construction:

Certified manufacturer of pressure equipment in accordance with Pressure Equipment Directive 97/23/EC Module D incl. Annex (AD 2000/EN 13480/ASME) and Pressure Equipment Directive 2014/68/EU
Certified manufacturer and welding company pursuant to the AD 2000 Regulations (HP 0) / DIN EN ISO 3834
Certified manufacturer of devices in potentially explosive atmospheres in accordance with Directive 94/9/EC (TÜV 05 ATEX 2762 Q) and 2014/34/EU

Certified exporter for Russia (TR CU 032)

Standards committee
We are actively involved in the continued development of international industrial standards. As a member of the committee for the DIN EN ISO 5167 standard for differential pressure transmitters, we are involved, for instance, in the revision of the first six parts, “general principles, orifice plates, nozzles, venturi tubes, wedge meters, and cone meters”. We are also a member of the Piping and Boiler Plant (NARD) committee, in which we are involved in further developing the DIN EN 12953-9 standard. This is how we aim to elevate the standards in manufacturing our measuring instruments to the next level.
