This instrument improves the quality of measurement of velocity and turbulence in a tidal channel. The measurement point is designed to be at hub height of a tidal turbine. From these measurements, a more accurate estimate of the forces applied to a tidal turbine by the flow can be gained. More certainty of loading on a tidal turbine means that the structure does not need to be overdesigned, hence reducing structural weight and cost. It will also improve estimates of the energy yield available at a particular location. The sensors are mounted on the Swansea University Self Recovery Instrument Frame(SUSRIF)and the frame could be used for other types of measurement.
