How to use a tide gauge
1. Balanced Tide; In the second half of the century, Newton used the law of universal gravitation to explain tidal phenomena and proposed the theory of equilibrium tides.   This theory was developed by Bernoulli; Euler et al; Research and Development; Upon investigation, it was found that; Further improvement has been made;.   The equilibrium tide theory assumes that; The surface of the ball is completely covered by seawater; And without considering friction and inertia;.   In  Under the influence of tidal force; The sea surface is far away; Open the original equilibrium position; And assuming that at any given moment, the sea surface is constantly in contact with; Tidal force and gravity; The synergy of forces; Vertical  Thus achieving the goal of being new at any time; The balance;.   Due to; Tidal Power; Periodic changes; Make the sea surface periodic; Sex  The rise and fall; Reduce Change  This state of the sea surface is called equilibrium tide;.   The equilibrium tide is completely hypothetical; The state of; Actual ocean tides; Due to being affected

Method of fixing tide gauge
1. Make three holes with a diameter of 4MM at an angular spacing of 120 degrees at the height of the "inlet hole"; Rust prevention measures should be taken for the fixed poles of the tide level indicator, antenna, and lightning rod.   The tide level indicator should be at least 5 meters above the ground.   The height of the lightning rod should be at least 1 meter higher than that of the omnidirectional antenna.

Analysis method of tide gauge
1. There are various methods for tidal analysis, including harmonic analysis, tidal height linear combination filtering, least squares method, and response analysis, among which tidal harmonic analysis is the most common.   Also known as harmonic analysis, it is a specific application of Fourier analysis.

Method of deploying tide gauge
1. After selecting the location for placing the tide gauge, all the legs of the base are driven into the seabed through seismic sinking to stabilize the base on the seabed;   After the earthquake subsides, place heavy objects on the bottom plate of the base to further secure it;   3. Fix the column in the column installation sleeve;

Usage of Tide Gauge
1. The use of a self-contained tide gauge is relatively simple, simply install it in a suitable location, such as a dock, buoy, or seabed base, and ensure that the sensor is fully submerged in water. Once installed, the tide gauge can automatically record changes in water level and store the data in internal memory or external devices.
2. What is tidal harmonic analysis? Tidal harmonic analysis is a method of tidal analysis. There are various methods for tidal analysis, including harmonic analysis, tidal height linear combination filtering, least squares method, and response analysis, among which tidal harmonic analysis is the most common. Also known as harmonic analysis, it is a specific application of Fourier analysis. Fourier analysis refers to a set of mathematical methods that expand any periodic function into a Fourier series and represent any non periodic function as a Fourier integral. The classic tidal analysis method, when applying this analysis principle, first records the constituent tides in the measured tidal level; ( Such as the Taiyin tidal system, the solar tidal system, etc; Separate and conduct harmonic analysis. Calculate the amplitude and phase angle of each tidal component, and after astronomical correction, obtain the harmonic constant of that tidal component. Tidal harmonic analysis can be used to calculate tidal changes during a certain period and analyze the tidal properties of the area.   Chinese name.
3. What are the ways to utilize tidal energy? Tides, as a natural phenomenon, have provided convenience for human navigation, fishing, and salt drying. As early as the 11th century, Britain, France, and Spain had waterwheels that utilized tidal energy. At that time, tidal waterwheels were used to absorb a small portion of the total potential energy and produce about 30-100 kilowatts of mechanical energy.   At present, the main way of utilizing tidal energy is through power generation.

How to use tide level measurement
1. To use tide level timing, the first step is to select a suitable measuring point located above the water surface and install the tide gauge at that position.   Attention should be paid to the height and position of the tide gauge during installation to ensure the accuracy of the data.   After installation, it is necessary to set the sampling time interval and sampling frequency according to the tidal conditions and measurement requirements.
