The advantages are low instrument cost, sturdy and durable, high degree of automation, high observation accuracy and good filtering performance. The disadvantage is that the well needs to be built during installation and the installation cost is high. It is only suitable for long-term fixed-point tide inspection on the shore; the acoustic tide gauge is Acoustic transmitting and receiving probes are placed at a fixed position above the sea surface, and the distance from the probe to the sea surface is calculated by detecting the duration of the sound wave emission to the sea surface echo returning to the sound probe, thereby obtaining the change of the sea surface with time. The advantage is that the cost is low and the degree of automation is high. The disadvantage is that the observation accuracy is lowered due to the beam angle effect (that is, the circular wave field acting on the sea surface during the sound wave reflection reflection process is not a point).

The fluctuation of the sea surface is calculated by detecting the pressure change of the seawater.
