Tide Gauge System
Measure Water Level with Confidence
What is a Tide Gauge?
A Tide Gauge is a device that measures how the water level changes during the day.
The sea level is not always the same. It goes up and down because of tides. A tide gauge records these changes and helps surveyors know the correct water level while carrying out a hydrographic survey.
Without tide data, water depth measurements may not be accurate.
Why is a Tide Gauge Important?
When survey teams measure water depth, the sea level may be higher or lower than normal.
A Tide Gauge helps correct these measurements so that the final survey data is accurate and reliable.
It is an important tool for hydrographic surveys, dredging, ports, harbors, and coastal engineering projects.
How Does It Work?
A Tide Gauge works in a few simple steps.
- The sensor is installed near the water.
- It measures the water level all day.
- The readings are saved automatically.
- The survey software uses this information to correct the depth data.
- The final bathymetric map becomes more accurate.
