Honeywell Fusion4 MSC-L Multi Stream Loading Controller

Product basic positioning and adaptation scenarios

Core positioning: A pre-set loading controller designed specifically for industrial terminal automation, with the core goal of improving loading throughput, shortening operation time, reducing measurement errors, lowering compliance costs, and ensuring safe, reliable, and accurate trade handover of media such as petroleum products.

Adaptation scenarios:

Road transportation: loading/unloading of tank trucks, loading of LPG/LNG tank trucks

Railway transportation: loading of railway tank trucks

Air transportation: aviation refueling

Storage and pipeline: storage transfer, ship refueling, pipeline transportation, transportation refueling

Core advantages: intuitive operation (icon driven interface), flexible deployment (modular design), convenient integration (multi protocol support), safety compliance (global explosion-proof certification), efficient maintenance (diagnostic dashboard+on-site upgrade).

Core functions and features

1. Loading control and mixing capability

Control mode: Supports four core modes: Straight, Ratio, Side Stream, and Sequential. It also supports internal/external additive injection control

Control algorithm: Adopting proportional integral feedforward (PI-FF) control algorithm, dynamically setting control points, optimizing valve control based on preset flow curve, reducing valve wear, improving control accuracy and repeatability

Interrupt recovery: Automatically recalculate the mixing accuracy after loading the interrupt to ensure that the delivered medium meets the specification requirements

Valve adaptation: compatible with digital valves, analog valves, and two-stage control valves, supporting precise parameter tuning

2. Operation and display experience

Display configuration: 8-inch WVGA full-color TFT display screen, 16:9 aspect ratio, adjustable backlight, supports clear display under strong light

Operating interface: Icon driven design, intuitive and easy to understand, significantly reducing training costs; Real time dynamic display of loading status, flow curve, and progress bar for quick monitoring

Language support: Covering 15+languages, including English (US/UK), Chinese (Simplified), Japanese, French, Spanish, German, etc

Quick start: boot time ≤ 1 minute, supports configuration file import, accelerates multi device deployment

3. Safety and compliance features
