MDOW Package Integration
Complete Loading Solution

One Package. One Controlled Transfer.

MDOW develops truck and rail loading / offloading systems around the complete operating sequence—not only the meter. The package coordinates field measurement, valves, grounding, loading arms, batch control and the data interfaces required by terminal operations.

Coriolis mass-flow measurement for accurate delivered quantity.
Low-flow start, full-rate transfer and controlled ramp-down.
Grounding, emergency stop and permissive-based interlocks.
Local batch authorization with offline operating capability.
Interfaces for DCS, ERP, weighbridge, access and queuing systems.
Fabricated, assembled and tested as a modular skid package.
Transfer Architecture

From Product Header to Loading Arm

The process train is configured around the fluid, loading rate, hazardous-area classification and terminal operating philosophy. Optional vapor return measurement can be added where required.

MEASUREMENTMass flow, pressure and optional differential-pressure monitoring.
CONTROLRegulating and shut-off valves execute the batch profile.
SAFETYGrounding, emergency stop and loading permissives protect transfer.
CONNECTIVITYBatch data is exchanged with terminal and enterprise systems.

Operating Workflow

Controlled From Dispatch Order to Final Record

The loading sequence can be linked with terminal logistics and safety processes so that authorization, transfer and reporting follow one traceable operating path.

01 PLANOrder & SchedulingImport the delivery order, assign the vehicle and manage the loading queue.
02 VERIFYAccess & SafetyConfirm driver, vehicle, training, inspection, weighbridge and access conditions.
03 CONNECTPrepare the BayManage keys, connect the loading arm and vapor return, and verify grounding.
04 AUTHORIZELoad the BatchUse card, code, QR or identity authorization to start the approved preset.
05 RAMP UPProtect the TransferStart at low flow, increase to the safe loading rate and supervise permissives.
06 RAMP DOWNFinish AccuratelyReduce flow near target, close the valves and account for overrun.
07 RELEASEDisconnect & WeighSecure equipment, return keys and perform final vehicle verification.
08 REPORTClose the TransactionSave batch data, issue documents and upload the completed transaction.

Local Intelligence

Batch Control at the Loading Bay

The intelligent batch controller presented in the supplied Endress+Hauser system material combines operational control with business connectivity. IT and OT functions may operate independently or together, supporting controlled transfer even when upstream business systems are unavailable.

Terminal Integration

Connect the Bay to the Business

The system can exchange operating and transaction data with the terminal's automation, logistics and management platforms. Interfaces are selected around the existing site architecture and each party's responsibility.

DCS / Safety SystemsOperating status, alarms, permissives and shutdown information.
ERP / SAPDelivery orders, batch completion and commercial transaction data.
Operator StationMulti-bay supervision, control, alarm handling and trend review.
Business StationOrder handling, transaction management and document generation.
Terminal LogisticsQueuing, access control, vehicle checks, weighbridge and e-seal interfaces.
Meter ManagementWeb-based diagnostics, parameter review and meter performance analysis.
Modular Engineering

Designed as a Complete Loading Skid

MDOW translates the process and control concept into a coordinated modular package. The skid arrangement brings piping, instrumentation, valves, electrical interfaces and maintainability into one model before fabrication.

Metering Performance

Accuracy Supported at Every Level

Measurement performance depends on the meter, process conditions, piping design, valve behavior, control logic and calibration strategy. MDOW coordinates these elements as one system.

Values shown are design targets stated in the supplied loading-system presentation. Guaranteed performance and applicable standards are confirmed for each project.
