Applications:

1. Fuel Management: Monitoring fuel levels to optimize consumption and ensure sufficient supply during voyages.

2. Ballast Control: Managing ballast water levels to maintain the ship's stability and balance.

3. Cargo Operations: Ensuring accurate loading and unloading of liquid cargo to prevent spillage and overloading.

4. Water Management: Monitoring potable water, waste water, and other water tanks to ensure proper operations and hygiene.

Considerations:

Accuracy: Different applications may require different levels of accuracy. For example, fuel management might need very precise measurements.

Environmental Conditions: The gauge must be suitable for the environmental conditions, such as temperature, pressure, and the presence of corrosive substances.

Maintenance: Consideration of how often and easily the gauge can be maintained or calibrated.

Integration: Ability to integrate with the ship’s existing systems for monitoring and automation.
