The KDG Mobrey MCU200 Electronic Liquid Level Control is a reliable marine liquid level monitoring and alarm system designed to detect liquid levels in various onboard tanks and automatically generate alarm or control signals when preset levels are reached. The system consists of an MCU200 electronic control unit and a stainless-steel level probe, providing accurate level detection even in demanding marine environments.

Widely installed on commercial ships, offshore platforms, and industrial facilities, the MCU200 continuously monitors liquid levels in bilge tanks, ballast tanks, fuel oil tanks, sludge tanks, service tanks, freshwater tanks, and other process vessels. When the liquid reaches the configured level, the controller activates alarm relays, pumps, valves, or other automation equipment, helping prevent tank overflow, dry running, or low-level conditions.

The front panel includes clear NORMAL, ALARM, and FAULT LED indicators, allowing engineers to quickly determine the operational status of the system during daily engine room inspections.

SM MARINE SERVICE™ supplies New, Reconditioned, and Fully Tested KDG Mobrey MCU200 Electronic Liquid Level Control Systems, including control units, probes, sensors, relay boards, electronic modules, spare parts, repair services, calibration, and worldwide technical support.

What Is the KDG Mobrey MCU200 Electronic Liquid Level Control?

The KDG Mobrey MCU200 Electronic Liquid Level Control is an intelligent liquid level monitoring and alarm system designed to detect high or low liquid levels in marine tanks. It combines an electronic control unit with a stainless-steel sensing probe to provide accurate, reliable, and maintenance-friendly level detection.

The MCU200 continuously monitors the liquid level inside a tank and activates alarms, pumps, valves, or shutdown systems whenever the liquid reaches a preset level. This helps prevent tank overflow, pump dry running, and other operational hazards.

The system is widely used on commercial ships because of its excellent reliability, simple operation, and long service life in harsh marine environments.
