Water Level

In more protected areas, the motions of the water’s surface can be measured in two ways: using a WaveGuide Height & Tide or a WaveGuide Water Level mounted on top of a pipe (stilling well version). 

With the WaveGuide Height & Tide the water level is measured at the point where it’s mounted (bridge, pool and so on). The WaveGuide Water Level version measures the water level in a pipe. This pipe can be left completely open, as there is no need for a small water entrance. Cleaning, as a result of marine growth is hardly required. The rapid motions of the water surface are filtered in the WaveGuide server, allowing measurements of faster phenomena like seiches (harbour oscillations).

With the available “Tide Processing Software” raw data and parameters can be requested and displayed on a computer’s web browser. All data or a selection thereof can be stored in a data logger. With a special stilling well antenna 150, 200, 250 and 300 mm pipe diameters are supported. Periods of 10 seconds and 1, 5 and 10 minutes are readily available (others on request).
