Cori-Flow Dosing Box for fuel/water additive dosing

The system is based on a fuel flow or water meter combined with an additive dosing unit, consisting of a second flowmeter directly controlling a pump, dosing an additive. These flow instruments function as a master-slave system withratio control. The fuel flow / water meter will be the master and the additive dosing box will follow the master with acertain ratio, where the additive will be injected into the fuel/water line according to the required rate ofppm’s/percentages.

The modular assembly of components has been integrated in a robust enclosure as a complete unit with fluid inlet and outlets, power supply, local HMI/PLC operation with touch panel and optionally remote access. In most cases the fuel oil / water meter will be mounted in existing fuel/water lines of the ship.

Basic functionality

· Dosing:

                Continuous additive dosing into fuel/water flow line, based on ratio control on preset ppm’s

· Reading:

                Fuel (water) flow, additive flow, (pressure), density, temperature, setpoint, ratio control (input slave

                factor and connection to external master signal), totalizers for consumption monitoring, alarms,

                configuration settings

· Trending (graph with time on x-axis):

                Flows, pressure, density, temperature, PID-controller output

· Adjustable:

                Setpoints (ratio), reset batch counter, (reset) alarms, instruments configuration settings (master + slave)

· Main menu:

                With trends and soft-buttons to activate screens for parameter change

Technical specifications
