Bed Profiling System
The 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. The 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.
Key features
- Utilises our traverse system to position the profiler in a 2D or 3D environment
- Operates both with and without water present
- Choice of laser or touch-sensitive probes
- Accuracy of ±0.5mm vertically and horizontally
- Positive non-slip drives
- Data stored in ASCII format

Digital Point Gauge (0-285 mm)
The digital point gauge measures steady state water levels on physical models. Conventionally this is done by using a small point or hook which is manually adjusted to touch the water surface and then a reading is taken using a scale or vernier. Our digital point gauge works in the same way but has a battery operated LCD display that makes it extremely easy to read. A quick release device allows fast positioning of the point to the water surface, and the final fine adjustment is made with a screw thread. The display reads directly in millimetres and can be set to zero at any position to allow relative measurements to be easily made.
Product range
The range of this product is 0 to 285mm. It is also available in the ranges 0-435mm and 0-585mm.Key features
- Simple to use
- Versatile display unit
- Rugged design
- Easy to read
Specification
- Range: 285mm
- Resolution: 0.01 mm
- Accuracy: 0.05 mm

Instrument Traverse System
The 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. Check the specification tab on the left for a typical specification.
Key features
- Positions a number of instruments within a flume or basin to a repeatable accuracy of ±0.5mm
- Supplied with a PC and software which controls the movement of instruments
- Lightweight, modular system
- All systems are designed to suit the client’s individual requirements for horizontal span and vertical movement
A typical specification would be:
Horizontal beam (x-axis)
- Maximum overall length: 6m
- Maximum travel: 5.8m
- Maximum velocity: 50mm/s
- Positional accuracy: ±0.5mm
Horizontal beam (y-axis)
- Overall length: 4m (dual motors required for lengths >2.0m)
- Travel: 3.8m
- Maximum velocity: 50mm/s
- Positional accuracy: ±0.5mm
Vertical beam (z-axis)
- Travel: 0.6m or 1.2m
- Maximum velocity: 25mm/s
- Positional accuracy: ±0.5mm
- Lifted weight of instruments: 5kg
- Supply voltage: 220V AC or 110V AC
In addition to the standard 2- and 3- axis systems, a second independent carriage can also be added to the horizontal beam.
