Radar-Operated Tide Level Sensor


This instrument uses radar technology to detect the sea level whose value is obtained by measuring the distance of the free surface of the water from the sensor body. Thanks to the use of a special algorithm managed by the control unit, the acquired data are processed in order to measure the level variations linked to the tidal phenomenon.

- Easy maintenance:
The advantages offered by the ETG radar tidal gauge are not limited to precision, but also include simplicity and speed of maintenance, due to the engineering of the sensor itself which simplifies its phases. The only preventive activity consists in checking the leveling of the sensor and in cleaning the target affected by the sensor. In fact, there must be no obstacles between the sensor emitter and the free surface of the water.

- Sturdy and reliable construction:
It makes it a long-lasting tool, safeguarding the customer's investment. The instrument does not drift due to aging and does not require periodic calibration. It is built in propylene with excellent chemical resistance, which makes it particularly suitable for operation in adverse conditions such as those typical of the marine environment.

The sensor can be equipped with an additional tidal gauge in combination, aimed at redundancy of measurement. The second tidal sensor can be of the piezometric or float type or itself of the radar type.
