Core offering

Westenberg Wind Tunnels & Measurement Systems designs and manufactures custom calibration wind tunnels (Eiffel and Göttinger types), flow measurement systems, and volumetric flow test stands for fluid flow calibration. The company operates a DAkkS-accredited calibration laboratory and provides on-site calibration, contract measurements, seminars, and consulting services for sensor manufacturers, calibration service providers, national metrology institutes, meteorological agencies, and defense customers worldwide.

Product overview

Westenberg Engineering operates two divisions: Westenberg Engineering (calibration laboratory and services) and Westenberg Wind Tunnels (wind tunnel and test stand manufacturing). The product portfolio centers on calibration wind tunnels in two main types — Eiffel (open-circuit, suction-type) and Göttinger (closed-circuit recirculating) — available in multiple models spanning velocity ranges from 0.05 m/s to 100 m/s and nozzle exits from 180 mm to 1,100 mm. Special-form tunnels include pressure wind tunnels, freejet tunnels, and acoustic tunnels. Supporting the wind tunnels are modular accessories including Flow Calculation System (Westibox), Low Speed Module, Laser Doppler Anemometer, Traversing System, Turntable, Volumetric Flow Extension, Fog Generator, Heat Exchanger, and operator workstations/racks. The test stand lineup includes the FMS (Flow Measurement System) series (FMS 50/100/250/490), Fan Test Stand, large Volumetric Flow Test Stands (up to 36,000 m³/h), and HFM Test Stand. Stationary measurement solutions include Nozzle Galleries, Venturi Nozzles, and Inlet Measurement Nozzles. The DAkkS-accredited calibration laboratory offers accredited calibrations for flow velocity and volumetric flow, while services include on-site calibrations, contract measurements (using 2D LDA), seminars/training, accreditation consulting, and measurement uncertainty calculations. The company has installed wind tunnels at major meteorological institutes, calibration service providers, and universities worldwide.

Brands

• Westenberg Wind Tunnels: Division specializing in development and manufacturing of wind tunnels, volumetric flow test stands, and flow measurement systems.

Products and services

• Eiffel-type Calibration Wind Tunnel (Windkanal nach Eiffel Bauart) Open-circuit suction-type wind tunnel with drive fan located downstream; air is drawn from the surrounding atmosphere via an inlet nozzle, passes through a settling chamber with flow straightener and damping screens, accelerates through the tunnel nozzle into a closed test section, then exits via a collector and diffusers. Used for sensor and anemometer calibration.
• Göttinger-type Calibration Wind Tunnel (Windkanal nach Göttinger Bauart) Closed-circuit wind tunnel with flow recirculation; fan is located in the return duct far from the test section. Air circulates through return corners with air-foil guides, settling chamber, nozzle, and open or closed test section. Provides lower power consumption, near-atmospheric test section conditions, and reduced sensitivity to external disturbances.
• Special-form Wind Tunnels (Sonderformen) Custom wind tunnel variants including pressure wind tunnels (Göttinger-type with closed test section regulated via compressed air network with automatic cooling to 20 °C), freejet tunnels (e.g., WK 817215-F covering 1-20 m/s), and acoustic wind tunnels (e.g., WK 860020-ELN with 600 mm nozzle exit, 0.5-20 m/s).

• HFM Test Stand (Heat Flow Meter Prüfstand) Heat flow meter test stand. Measurement range: 20-850 kg/h; dimensions: 2,200 × 2,400 × 930 mm.
• Nozzle Gallery (Düsengalerie) Stationary nozzle array system for volumetric flow calibration with customer-specific measurement ranges, number of nozzles, and dimensions.
• Venturi Nozzle (Venturi-Düse) Stationary Venturi nozzle for volumetric flow measurement. Typical accuracy: 1.5%.
• Inlet Measurement Nozzle (Einlaufmessdüse) Stationary inlet measurement nozzle for flow calibration and reference measurement.
• Laser Doppler Anemometer (LDA/LDV) Laser Doppler velocimetry system for non-intrusive flow measurement. Laser power: 75-500 mW; wavelength: 532 nm; accuracy: 0.2%. Developed in partnership with ILA R&D GmbH.
• Flow Calculation System (Westibox) Flow measurement device based on the differential pressure principle (Wirkdruckprinzip) using a Prantl tube. Measurement range: 0.5-100 m/s.
• DAkkS Calibration Laboratory Services DAkkS-accredited calibration laboratory (DIN EN ISO 17025:2018) offering accredited calibrations for flow velocity (0.1-70 m/s, 0.5-0.7% uncertainty) and volumetric flow (80-4,300 m³/h, 1.5% uncertainty) of gases. Also offers factory/ISO calibrations for flow velocity, volumetric flow, differential pressure, temperature, and relative humidity.

Broad incumbents

• Vaisala Oyj: Vaisala is the global leader in meteorological and environmental measurement instruments and is also a Westenberg customer (Göttinger wind tunnel at Vantaa, Finland, 2021). It is comparable because it both consumes and competes in the traceable flow-calibration space, and could vertically integrate calibration capabilities in-house.
• Campbell Scientific: Campbell Scientific designs and manufactures environmental and meteorological measurement systems, including anemometers and weather stations, sold to national weather services and research institutes. It is comparable because it serves the same meteorological and metrology customers as Westenberg and could either purchase calibration wind tunnels or internalize calibration capability in-house.
• Endress+Hauser: Endress+Hauser is a global leader in industrial process measurement instruments, including flow and calibration. It is comparable because it serves flow measurement and calibration customers worldwide with broader instrumentation portfolios, and competes at the calibration-services layer with Westenberg's accredited offerings.
• Fluke Calibration: Fluke Calibration (part of Fortive) is a global incumbent in calibration standards, instruments, and services across pressure, temperature, flow, and electrical parameters. It is comparable because it serves the same accredited calibration laboratory customer base as Westenberg, offering reference standards and traceability services with broader scope but less specialization in calibration wind tunnels.

Direct peers

• Druck (Baker Hughes): Druck, part of Baker Hughes, designs and manufactures pressure and flow calibration instruments and laboratory standards. It is comparable because it supplies calibration reference equipment and traceable measurement solutions to national metrology institutes, calibration service providers, and industrial customers—the same buyer segments served by Westenberg wind tunnels and FMS series.
• Aerolab: Aerolab designs and manufactures wind tunnels, flow measurement test sections, and aerodynamic test facilities for aerospace, automotive, and industrial research. It is comparable because it operates in the same custom wind-tunnel design and build market as Westenberg, with overlapping expertise in calibration-grade flow test sections and instrumentation.
• Mensor (AMETEK): Mensor, an AMETEK business, manufactures precision pressure and flow calibration instruments and reference standards for metrology laboratories. It is comparable because it targets the same accredited calibration and metrology institute buyers as Westenberg, with overlapping measurement uncertainty benchmarks and ISO 17025 positioning.
• ILA R&D GmbH: ILA R&D is Westenberg's technology partner for Laser Doppler Anemometer and other optical flow measurement systems. It is comparable because it develops calibration-grade flow velocity instrumentation (LDV, DGV, FRS) and supplies it to scientific and industrial customers, overlapping with Westenberg's accessory portfolio.
• KRIWAN Industrie-Elektronik GmbH: KRIWAN is a German manufacturer of industrial sensors and protection electronics, and a Westenberg customer (Göttinger wind tunnel WK 8300x30040-G). It is comparable because it operates an in-house sensor calibration capability and represents the OEM customer archetype (sensor manufacturer requiring traceable wind-tunnel calibration) that drives Westenberg's core revenue.
• Testo Industrial Services AG: Testo Industrial Services is one of Europe's largest accredited calibration service providers and a Westenberg customer (installations in Egg, Switzerland, 2025 and Istanbul, Turkey, 2023). It is comparable because it operates accredited calibration labs and resells/extends Westenberg wind tunnels for flow and volume calibrations—mirroring Westenberg's services-plus-hardware model in adjacent geographies.
