SEIKO Flowcontrol

What SEIKO Flowcontrol does

SEIKO Flowcontrol is an Austrian family-owned industrial manufacturer (SEIKO-Flowcontrol Ges.m.b.H.) specializing in differential pressure (DP) flow measurement technology. Founded in 1968 in Vienna and now headquartered in Stockerau, Austria, with engineering and production concentrated in Blatnice pod Svatým Antonínkem, Czech Republic, the company designs and produces custom-engineered flow elements including orifice plates, ISA 1932 nozzles, long-radius nozzles, Venturi nozzles and tubes, pitot probes, ASME PTC-6 flow sections, cone meters, wedge meters, and quarter circle nozzles. Its products serve power generation (thermal, fossil, nuclear, CHP, solar, hybrid), oil and gas (wellhead to refinery), and industrial process sectors (chemical, steel, paper), with named customers spanning SIEMENS, TOSHIBA, HITACHI, BASF, OMV, Linde, GE Vernova, Wood, Wien Energie, Kanadevia INOVA, John Cockerill, NOOTER ERIKSEN, Andritz, KROHNE, and Empresarios Agrupados.

SEIKO's competitive position rests on vertically integrated in-house engineering and manufacturing. The company employs CONVAL flow-calculation software and SolidWorks 2D/3D modeling for design, and operates CNC machining, EN/ASME-certified welding, heat treatment up to 10 meters, non-destructive testing (ultrasound, PMI, X-ray up to ASME Level 3), and pressure testing up to 1050 bar. Calibration is delivered through its VCS (Venturi Calibration Services) partnership at the Czech site, with SEIKO building the proprietary hot-water (80°C) calibration rig capable of triplicate Reynolds numbers versus cold-water calibration and an uncertainty of 0.10%. The company holds ASME S-Stamp, ISO 9001/14001/45001, CE marking (Modules D/D1, E/E1, H, H1), AD2000-HP0, and PED 2014/68/EU certifications, with compliance also to AGA, NORSOK, NACE, and CRN standards.

Revenue is generated through one-time sales of customized DP flow elements, professional engineering services (flow calculation, basic and stress design, isometric checking, hydrostatic testing, calibration, corrosion protection), and accessory hardware (thermometer protection tubes, valves, condensate pots, thermowells). Pricing is quote-based and not publicly disclosed. The go-to-market combines direct enterprise sales to EPCs, OEMs, and plant operators with a regional agent and distributor network covering 14+ countries across Europe, the Americas, the Middle East, and Asia-Pacific. The company has accumulated 20,000+ installations globally over more than 60 years under continuous family ownership, with second-generation leadership currently in place.
