CORI-FLOW Dosing Box for additive dosing into fuel lines and ballast water on ships

The CORI-FLOW Dosing Box is a high-integrity solution for the precise injection of additives into marine fuel lines and ballast water systems. The system utilizes a sophisticated Master-Slave control logic to ensure chemical concentrations remain constant regardless of fluctuating flow rates.

Coriolis-Based Ratio Control: The primary fuel or water meter acts as the "Master," providing real-time flow data to the dosing unit. The secondary Coriolis flow meter - the "Slave" - directly modulates the dosing pump using high-speed closed-loop control. This ensures the additive is injected at an exact PPM (parts per million) or percentage ratio with laboratory-grade repeatability.
Integrated Process Control: All critical components are housed within a reinforced, modular enclosure. The system includes a local PLC/HMI touch panel for real-time monitoring and parameter adjustment, with the option for secure remote access for shore-based fleet management.
Non-Intrusive Integration: Engineered for minimal downtime, the dosing box is designed to interface with existing flow meters and infrastructure already installed on the vessel, simplifying the retrofitting process.

Core Functionality & Process Analytics

The CORI-FLOW system provides a comprehensive interface for real-time process monitoring and precision chemical management.

Closed-Loop Ratio Dosing: Delivers continuous additive injection based on high-precision ratio control. The system maintains preset PPM/percentage concentrations by dynamically adjusting to fluctuating flow rates in the primary fuel or water line.
Multivariable Data Acquisition: The system monitors and records critical process variables to ensure chemical stability and equipment health, including:
Mass & Volumetric Flow (Master and Slave)
Fluid Density & Temperature (Coriolis-based)
System Pressure & PID Controller Output
High-Resolution Totalizers for precise consumption auditing.
Advanced Process Trending: Integrated graphical displays provide real-time visualization of flows, pressure, and density over time. This allows engineers to identify transients and ensure the dosing remains within strict tolerance limits.
Dynamic Parameter Optimization: Authorized users can adjust ratio setpoints, reset batch counters, and configure master/slave instrument parameters through a secure, multi-level interface.
Intuitive HMI Navigation: The primary dashboard features soft-button navigation for rapid access to configuration screens, alarm management, and historical performance trends.

FAQ: System Precision & Technology

How does the system ensure the correct chemical concentration?

The system utilizes a Coriolis-based Master-Slave architecture. The primary flow meter (Master) measures the fuel or water flow, while the CORI-FLOW dosing unit (Slave) monitors the exact mass of the additive being injected. Through high-speed closed-loop ratio control, the system maintains a precise PPM (parts per million) concentration, even during rapid fluctuations in the main flow line.

What variables can the system monitor beyond flow rate?

Unlike standard volumetric pumps, our system provides multivariable data acquisition. It tracks and logs mass flow, fluid density, temperature, system pressure, and totalized consumption. This data is essential for both technical performance analysis and environmental compliance reporting.

FAQ: Installation & Integration

Is it possible to retrofit this system into an existing engine room?

Yes. Our dosing solutions are engineered for non-intrusive integration. The dosing box is a modular unit that typically interfaces with existing flow meters and infrastructure. Because the components are housed in a robust, compact enclosure, it can be installed in tight spaces common in maritime environments.

Can the system be monitored from onshore?

Yes. The system supports secure remote access via Ethernet/Internet. Fleet managers can monitor dosing trends, consumption data, and system health in real-time from a shore-based office, allowing for better chemical inventory management and troubleshooting.

FAQ: Reliability & Maintenance

How does the system handle equipment failure?

The system is built with redundancy handling and advanced alarm logic. In the event of a signal loss or hardware malfunction, the system can trigger secondary fail-safes or alert the bridge immediately via the integrated PLC/HMI, ensuring that untreated fuel or water does not move through the system unmonitored.

What are the maintenance requirements for the CORI-FLOW box?

The system is designed for ultra-low maintenance. Because Coriolis meters have no moving parts in the flow stream, they are less susceptible to wear and tear compared to traditional mechanical meters. Routine maintenance is largely limited to standard pump inspections and occasional filter cleaning.
