We specialize in the transfer of the very latest technology and techniques from the aerospace research laboratories to the commercial marketplace. We provide capability and expertise developed over decades of experience at the forefront of experimental fluid mechanics and turbulence research.


Cutting-edge science


Our technology is derived from the leading scientific activity taking place in the Centre for Aerodynamics and Environmental Flow at the University of Surrey, developing new systems and refining older techniques to address real-world measurement problems.

Multi-hole velocity and vorticity probes


We produce a range of high-precision multi-hole velocity probes, fabricated either in stainless steel or acrylic, depending on the required application. All probes may be designed with an integraged static pressure sensing sleeve for direct differential pressure measurement.

  • Rakes, five- and seven-hole probes; custom probe configurations available
  • 12- and 37-hole omnidirectional probes
  • High-bandwidth Pitot and total pressure probes for turbulence measurement applications
  • Low-cost, 3D-printed integrated probes for very-large-array applications
  • Probe calibration systems and services

Thermal anemometry systems


Our low-cost, medium-bandwidth constant-temperature and constant-current anemometry systems offer highly competitive performance for a fraction of the cost of high-fidelity systems, and are ideal for lower bandwidth turbulence measurements or large-array applications.

  • Miniature hot-wire probes
  • High-precision, high-bandwidth constant-current anemometers with active noise cancellation
  • Ultra-small medium-bandwidth constant temperature anemometers
  • High-durability, weather-hardened thermal anemometry systems for wind anemometry field measurement stations

Pressure sensing systems


Our pressure measurement systems offer a high-functionality, customizable and low-cost alternative to miniature pressure scanners and mechanical multiplexers, using the very latest in sensing technology available.

  • High-precision, high-bandwidth, variable-range 64-channel pressure scanners with hot-swappable transducer cards
  • Surface-flush, high-resolution (3 x 3 mm) pressure sensing pads
  • Rapid-prototyping of models, with model-integrated surface pressure arrays
  • Networked data acquisition and telemetry systems

Measurement instrumentation


Our low-cost, high-functionality measurement instrumentation systems were specifically designed for inter-compatibility, using our own robust RS-485 network communications protocols to ensure reliable transmission and data transfer even in the noisiest environments.

  • Networked data acquisition and radio-telemetry systems
  • Bespoke sensing, acquisition and data management systems
  • Automated experimental calibration and measurement systems
  • Full metadata capture and archiving capability
