Description
SF-CONTROL
LEVELDATIC
TYPE: CU 21
CENTRAL UNIT
NO: 030
DRWG: LD 300 500
REF: TP 1105
The SF-Control CU 21 is the central processing and control unit within the Leveldatic level monitoring system, a purpose-built marine automation solution designed to manage and supervise liquid level measurement across onboard tanks and spaces. As the core intelligence of the Leveldatic system, the CU 21 receives input signals from level sensors and transmitters, processes this data, and outputs control commands to connected displays, alarms, or actuators. Marine control systems of this type are critical for safe and efficient vessel operations, supporting ballast management, bilge monitoring, fuel tank supervision, and cargo liquid level control. Drawing reference LD 300 500 and internal reference TP 1105 identify this unit within the SF-Control engineering documentation framework.
Key Features
✓ Functions as the central processing unit of the SF-Control Leveldatic level monitoring and control system, coordinating signal input and system output.
✓ Technical specifications including supply voltage, signal range, and response time are subject to confirmation based on drawing LD 300 500 and system configuration.
✓ Designed for integration within the Leveldatic system architecture, compatible with associated SF-Control sensors, display panels, and remote indicators typical of this product family.
✓ Intended for installation in a protected onboard environment such as a control room, machinery space console, or dedicated instrumentation cabinet — mounting configuration subject to original installation drawing.
✓ As a central unit within a continuous level monitoring system, the CU 21 is a key replacement component when servicing or restoring Leveldatic installations aboard vessels.
Marine Applications
✓ Ballast water system monitoring aboard bulk carriers, tankers, and general cargo vessels requiring accurate tank level supervision.
✓ Fuel oil and fresh water tank level control on merchant vessels, ferries, and offshore support vessels.
✓ Bilge level monitoring systems on vessels where automated detection and alarm functions are required for safety compliance.
✓ Cargo liquid level management on chemical tankers and product tankers where precise measurement and centralised control are operationally essential.
✓ Integrated automation systems on platform supply vessels, dredgers, and other specialised craft utilising SF-Control Leveldatic instrumentation.
