Akamina Wave Height Gauge Test Results

We completed a suite of tests to validate the performance of the Akamina Wave Height Gauge. The test suite included:

The results of these tests using the AWP-24 are now available for download. Below is a short description of the tests performed. The complete test descriptions and test results are included in the download.

Calibration test: calibration of wave height gauges involves acquiring a data set of output voltages at known water depths and then computing the linear relationship between voltage and depth. By using more than two points, we can look at the error between the calibration points and the best-fit straight line.

Background noise test: this test involves obtaining a short data sample and looking at the difference between the minimum and the maximum of the sample as well as the standard deviation of the data. We completed this test on a wave height gauge attached to a short length of instrumentation cable as well as on a wave height gauge attached to 60 m (200 ft) of instrumentation cable. This provides a view of the gauge noise as well as the effect of long distances between the gauge and the data acquisition system on noise.

Short-term drift test: this test involves placing a wave height gauge in very still water and acquiring a data sample for a period of 1 hour. If temperature is constant, the measured wave height should be constant over the hour.

Long-term drift test: this test involves placing a wave height gauge in very still water and acquiring data for a 72 hour period. Since the temperature of the electronics will vary with room temperature, we expect to see some low frequency drift caused by temperature. Temperature is acquired at the same time as wave height so it is possible to look at the wave height change at the same time as temperature.

Interference test: in this test we investigate the interference between adjacent wave height gauges. The test procedure involves placing one gauge in very still water and then raising and lowering a second gauge into the water within 15 cm of the first probe. The change in the output of the stationary probe gives an indication of the amount of interference between the two gauges.

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.
