Hydraulic Instrumentation

The Water Research Laboratory has over 50 years experience in the research, investigation and application of fundamental and applied civil engineering hydraulics. This field of expertise encompasses performance assessment of hydraulic structures such as dam outlet works, energy dissipators, ocean outfalls, spillways and levees and plants such as pump stations, hydro and thermal power stations, water and wastewater treatment plants. WRL also has a depth of experience and equipment for the accurate measurement of flows and flow patterns.

As well as having a long history in hydraulic research, WRL continues to develop and use state-of-the-art instrumentation to undertake its investigations. Such equipment includes:

  • Particle image velocimetry (PIV) using non-coherent and laser light sources
  • Laser induced fluorescence (LIF) measurements of aqueous concentration and sediment particle fields
  • Suspended sediment particle sizers
  • Acoustic techniques for measuring turbulent fluid stresses (Sontec ADVs and RDI ADCPs)
  • Conductivity measurements of bubble size and speed in multiphase flows
  • Conductivity measurements of aqueous concentration fields

In addition, WRL possesses a wide range of conventional hydraulic instrumentation including:

  • Automatic rain gauges
  • Water sampling equipment
  • Water level monitoring equipment
  • Weirs and flow measurement structures
  • Electromagnetic flow meters
  • Conventional current meters and
  • Turbidity meters
  • Air flow monitoring equipment
