What S.k.i. Schlegel & Kremer Industrieautomation Gmbh does

S.K.I. Schlegel & Kremer Industrieautomation GmbH is a German Mittelstand manufacturer specializing in differential pressure-based industrial flow measurement technology for gases, vapors, liquids, and steam. Founded in 1990 by Michael Schlegel and Friedhelm Kremer and headquartered in Mönchengladbach, the company designs and produces averaging Pitot tube sensors (SDF series), calibrated flow meters (AccuFlo LPD, HMP, Zero, and QAL lines), differential pressure transmitters, and the AccuMind universal flow computer, alongside complementary accessories such as the LSE-HD air back-purging unit and Thermosafe enclosures for harsh environments. Its proprietary AccuFlo Zero automatic zero-point calibration technology (patent-pending) and BMWi-funded AccuFlo HMP for short straight pipe runs are key differentiators, and the company holds QAL1 (EN 15267) and MCerts certifications that enable its instruments to be used in legally mandated emissions monitoring applications.

The company operates a DAkkS-accredited water calibration laboratory (DN15–DN300, 0.3–800 m³/h, reference accuracy up to 0.1%, traceable to PTB), which underwrites both internal product qualification and a third-party calibration services revenue stream. It sells custom-quotation-based hardware and professional services directly to industrial customers while leveraging an international sales-partner network across multiple countries, complemented by participation in the BMWi German Energy Export Initiative and relevant trade shows. Customer end-markets span power generation, environmental/emissions monitoring, steel and metallurgy, chemical and petrochemical, oil and gas, shipping (including LNG applications with named reference DSME), pharmaceutical, food production, paper and pulp, automotive utilities, and building materials.

S.K.I. remains privately held by the founding families, transitioned to second-generation leadership under Daniel Schlegel in 2023, and complements its physical product portfolio with cloud-based SKI WebApps engineering calculation tools (sensor sizing, IAPWS 97 water/steam properties, technical gas properties, and AGA 8 natural gas properties). Revenue is generated through hardware sales, accredited calibration services, and on-site installation, commissioning, and maintenance support under quotation-based contracts, with no public funding, M&A, or revenue disclosure available.
