Abstract: The liquid level telemetry system is one of the core systems of a ship. The measurement accuracy of the ship liquid level telemetry system will gradually decreases with the increase of the ship age, and faults will also occur. It will affect the crew's monitoring of the liquid level, and thus affect the safety and stability of the ship navigation to a certain extent. This paper introduces the repairing process of the liquid level measurement for a comprehensive supply ship, and introduces and analyzes the liquid level telemetry system from the maintenance process, fault analysis and determination of the maintenance plan. It can provide a certain reference for the future ship repair engineering in the analysis and demonstration of the repair level and repair plan .

Key words: liquid level telemetry, sensor, maintenance, fault, Programmable Logic Controller (PLC)
