Akamina Wave Height Gauges


Akamina's wave height gauges lead the industry in accuracy and ease of use. The gauges measure depth of water by measuring changes in capacitance caused by changes in water depth. Akamina's wave height gauge electronics measure water level using digital techniques. For convenience and ease of integration with existing data acquisition systems, the AWP-24-3 uses a digital-to-analogue back end to provide a high-level voltage output signal. With the introduction of the AWP-300, clients now have the option of obtaining the wave height measurements over a digital multi-drop communication bus. This simplifies cabling and completely eliminates digital-to-analogue and analogue-to-digital conversions in the measurement cycle.

Akamina's AWP-24-3 Wave Height Gauge is our next generation capacitance wave height gauge. It is a reliable and highly linear and accurate instrument for the measurement of wave heights and water levels. The new AWP-24-3 incorporates all the features of the AWP-24-2 and our first generation device, the AWP-24, and: * with one button setup and configuration , you no longer need to set any jumpers to configure the device. It is all done automatically with the push of a button.

For more information about the AWP-24-3 and the AWP-24-3-E, click here.

Please note that the AWP-24-2 and the AWP-24 Wave Height Gauges have been superseded and are no longer available for sale. We will continue to support them for our existing customers.

AWP-24-2 Superseded : for archived documentation please refer to AWP-24-2.

AWP-24: Superseded: for archived documentation please refer to AWP-24-SP.


Akamina's newest in the AWP-300 Series is our latest addition to our line of outstanding capacitance wave height gauges. It has the same reliable and highly linear and accurate instrument for the measurement of wave heights and water levels as the AWP-24 Series but with a digital interface. We have added a CAN Bus interface to simplify cabling, reduce noise and allow remote management: * with the new AWP-300-3, configuration is as simple as the click of a mouse, there are no jumpers to configure and there is no need to open the enclosure.

Akamina supplied a system of 15 waterproof wave height gauges to the Port and Airport Research Institute (PARI) in Tokyo, Japan. The system is used for directional wave measurement on their Hiratsuka Tower (close-up view ).


WaveGen-Studio and the ADQ-1000 provide a complete solution for your data acquisition needs. Akamina's system uses a network of connected servers for control capabilities and the acquisition of data which is controlled by WaveGen-Studio. For more information please read more at WaveGen-Studio and ADQ-1000 .


Akamina has the exclusive license to GEDAP - Generalized Experiment control and Data Acquisition Package - developed by the National Research Council Canada. GEDAP is a well-proven, complete software solution for physical modelling in hydrodynamic laboratories. GEDAP brings wave synthesis and wave data analysis with sophisticated plotting capabilities to the Akamina data acquisition and control offering.



Akamina completed the design, fabrication, installation and commissioning of the new portable wave generator in the Large Area Basin at the National Research Council Canada . This system features a portable, modular design consisting of 9 modules with 8 piston-mode segments per module. The drive system includes a regenerative power supply with an inverter to drive a transmission system that includes a synchronous motor, lead screw and rotating ball-nut. The controller and the servo drives for the 8 segments in a module are connected on a SERCOS III loop. The control system was featured in the "Sercos Makes Waves" article on the Sercos.org website.

The wave generator control system provides support for active wave absorption (reflection compensation) for both unidirectional and multidirectional waves. Other enhancements include improvements in sidewall reflection techniques and second-order wave generation.

In 2016 Akamina completed the design, fabrication, installation and commissioning of a 48-segment facility for the Offshore Technology Research Corporation at Texas A&M in College Station, Texas, USA. This was an upgrade project in which the mechanical and hydraulic drive subsystems were already in place. The upgrade included the design and fabrication of custom control hardware and software as well as data acquisition hardware and software. Installation, integration, commissioning and training were carried out on-site in College Station. Akamina's WaveGen-Studio with GEDAP software were supplied for wave generation and data analysis.


Akamina completes the design and the successful installation of 56-segment wave generator control system upgrade. The upgrade included custom control hardware and software as well as data acquisition hardware and software. This work was done for EDF - Laboratoire National d'Hydraulique et Environnement (EDF-LNHE) in Chatou, France.
