Our bed profiling system is used to assess the effect flowing water has on mobile sediment beds. It is available with a choice of probes to suit a wide range of applications.
Our bed profiling system is the result of much development work by HR Wallingford to meet the exacting requirements of hydraulic modellers and to ensure a high degree of reliability.
It utilises our traverse system to position the profiler in a 2D or 3D environment.

Our instrument traverse system
Our instrument traverse system is used to move a range of physical modelling instrumentation to a variety of different positions within a flume or basin in either two or three dimensions.
The instruments are secured to the vertical axis of the system, using a variety of fixings. The vertical axis is attached to a carriage which moves along a fixed horizontal beam to allow positioning of the instruments anywhere within the flume or basin. The traverser can be controlled by a software application that logs the exact time-stamped position of the instruments to an accuracy of ±0.5mm in both vertical and horizontal axes. A stepper motor with an integral encoder is used to drive each axis into position along the carriage using a toothed belt arrangement.
Our Instrument Traverse Systems are individually designed for each application. See Specification for an example of a typical specification.
