Tide Gauge

A tide gauge is a device for measuring sea level and useful for detecting tsunamis. Sensors continuously record the height of the water level with respect to a height reference surface close to the geoid. Water enters the device by the bottom pipe and Hydrostatic Submersible pressure type level sensors measure its height and record it in to the Data logger memory with date and time stamp. Tide gauges are used to measure tides and quantify the size of tsunamis. The measurements make it possible to derive the mean sea level. 
    “Virtual” make Automatic Tide Gauge reflect state of the art in micro controller based instrumentation design. The Two Level sensor (One each Non-contact Radar Type and contact pressure type sensors) can be attached with this data logger for the collection of real time data automatically. The micro controller has its internal memory along with, a real time clock with an LCD (16 X 2) to display the instrument status. Data file is saved in Microsoft’s Excel.
