Marine, Naval, Hydrodinamic and OceanographARCboat
The ARCboat is a remote controlled boat that is used to collect river and estuarine data including flow, depth and suspended sediment concentrations. It was developed in partnership with end-users and perfected to meet their exact needs. The boat can carry a variety of Acoustic Doppler Current Profilers (ADCP) and other instruments when required.
HR Wallingford provides outstanding customer support throughout the ownership of an ARCboat, from delivery to ongoing training and support.
Key features
- Can carry a variety of ADCPs and other instruments
- High quality data collection with minimal underhull air entrainment
- Robust and reliable design
- Excellent manoeuvrability
- Designed with operator safety in mind
- Lightweight and easy to transport
- Unique detachable bow
- Can also be used to measure environmental conditions in lakes

Marine, Naval, Hydrodinamic and OceanographARCboat Lite
This new, smaller lighter solution shares many of the features of the original vessel, but we have optimised it to carry out bathymetric and river current surveys in lower flow environments.
With a robust, lightweight hull, the ARCboat Lite has been specifically designed for use by a single person. Its detachable bow and grab rails make it easy and safe to handle, deploy and recover from survey sites.
High manoeuvrability and shallow draft combine to allow the ARCboat Lite to reach more of a survey site than has been previously possible.
The ARCboat Lite is built around a central moon-tube, which not only provides strength at the core of the vessel, but can also accommodate a wide range of sensors, such as SBES and ADCP, from a wide range of manufacturers. Other survey instrumentation, such as the top-box and communications equipment, is housed in the purpose designed hull recess.
The ARCboat Lite is an highly effective alternative to larger, more expensive survey vessels.

Marine, Naval, Hydrodinamic and OceanographBed 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
- Easy to install

Marine, Naval, Hydrodinamic and OceanographData AcQuisition software (HR DAQ)
The Data AcQuisition software (HR DAQ) is used to collect and analyse data from a variety of instruments used in physical models such as wave gauges, Acoustic Doppler Velocimeters (ADV) and pressure sensors.
Product features:
- Specifically designed for wave analysis
- Instrument calibration
- Data collection
- Spectral analysis
- Statistical and wave counting analysis
- Reflection analysis
This comprehensive Windows based data acquisition and analysis program, suitable for 64 analogue input channels, is project based and is split into three sections.
Calibration and scaling of inputs
The calibration section allows the modeller to calibrate any instruments installed in physical models that require regular in-situ calibration, such as resistance type wave probes. It also allows the modeller to enter factory calibrations for other sensors such as pressure sensors.
This section creates calibration files for use with the acquisition and analysis sections. It provides a comprehensive set of facilities for setting up the calibration files that are used to convert the analogue voltage signals in the model, to data at full scale, assuming Froude or Reynolds scaling.
Data acquisition
HR DAQ is set to collect raw data for a specified period of time at a specified frequency.
Data analysis
After the data has been collected, HR DAQ can be used to perform a number of analysis routines. The principal analysis program includes two routines; one is a Fast Fourier Transform spectral analysis and the other a statistical one.
Specification
Calibration routine:
- Labelling of input channels
- Automatic calibration with Linear Least Squares fit shown for each channel
- Automatic setting of zero levels
Data collection:
- Sampling frequency 1-500Hz
- Monitoring of channels during data collection
- Trace of all channels displayed or turned off as necessary
- Elapsed time and time to completion
- Requires compatible Analogue to Digital (A/D) converter
Data analysis:
- Spectral analysis
- Energy density
- Hs m0, m2, m4, Tp
Statistical analysis:
H1/3, Tm, Standard deviation, Variance, Reflection analysis, Bulk reflection coefficient, Incident and reflected spectra
Hardware/software requirements:
- Desktop or laptop with Quad Core processor
- Software can be downloaded directly from our web-server
- Windows-based environment operating system
- One user licence activation code provided per computer

AccessoriesDigital Display Unit for Water Level Gauges and Transducers
The digital display unit is for use with individual gauges and transducers. It contains a digital panel meter, which has a 0-10V output and a serial RS 422/485 connection. A separate power supply unit allows the instrument to be used with either 110V AC or 220V AC supplies.
It is supplied with a case and 0 – 5V output.
Display
- 14mm high brightness LED
- Display supply: 24V DC (90-250V AC adaptor supplied)
- Display output – analogue: 0-10V, 0-20mA or 4-20mA
- Display output – serial comms: RS422/485

Marine, Naval, Hydrodinamic and OceanographDigital 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
