Float-Operated Tide Level Sensor


The float-operated tide level sensor is a shaft encoder which, connected to a float by means of a steel rope, makes it possible to detect the movements associated with the tidal phenomenon with very high precision. The sensor is equipped with a float that can be customized in size and weight, which will be installed inside existing or newly supplied stilling wells. The sensor can also be supplied with a Mil-Spec military connector.

- Measurement principle:
The shaft encoder technology on which this sensor is based is a very simple measuring principle. The sensor is attached to a float via a cable. The float, following the level of the tide, will move the cable which will consequently move the sensor, providing the level data as an output.
- Easy maintenance:
The advantages offered by the floating ETG tidal sensor are mainly linked to the simplicity of the measurement principle.
- Sturdy and reliable construction: finally, this makes it a long-lasting tool, safeguarding the customer's investment. The instrument does not drift due to aging and can be easily verified in the field using level instruments calibrated for the purpose. The sensor can be supplied with a military standard output connector.

The installation of the float tidal gauge is simple and requires the installation of the float supplied with the sensor inside a specially prepared still-pipe.

The sensor can be equipped with an additional tidal gauge in combination, aimed at redundancy of measurement. The second tidal sensor can be chosen with a radar (non-contact), piezometric or float measurement principle.
