Scope

The pressure tide gauge (hereinafter referred to as the instrument) is mainly used for measuring tides (water levels) in oceans, rivers, and lakes. Its principle is that the pressure sensor senses the relative changes in water level, and the data is output digitally by the terminal. It has functions such as automatic storage, digital tube display, and microcomputer printing records. The instrument is mainly composed of a pressure sensor, a measuring instrument, and a data transmission system. The pressure sensor is divided into spring-type pressure sensors, crystal pressure sensors, etc.
