Metering skid — Pressurised LPG
A pressurised-liquid metering skid designed for safe and accurate loading of liquefied petroleum gas, keeping product in the liquid phase throughout the metering and control train.
Product overview · LNS-MS-LPG
The LineSig LNS-MS-LPG is a modular skid-mounted tanker loading metering system developed for controlled and traceable transfer of liquefied petroleum gas from terminal storage or transfer headers to road, rail or marine loading interfaces. The standard architecture is based on Coriolis mass flow measurement together with local explosion-proof batch control, flow regulation, pressure monitoring, static grounding, pressure/temperature transmission and other loading safety interfaces.
For LPG service, the configuration emphasises accurate batch measurement, clean flow conditioning and loading safety, with a hydraulic design that maintains adequate liquid pressure through the skid to prevent flashing. Final size, flow range, pressure class, materials, meter model, batch controller certification and loading interface are selected against the actual project datasheet and hazardous-area requirements — Coriolis is preferred, not automatically mandatory.
Design
Inlet isolation → Strainer/filter → Air eliminator or gas separator where applicable → Pressure/temperature measurement → Coriolis mass flowmeter → FCV/batch control valve → Check/isolation → Loading arm or hose interface, with vapour recovery where applicable.
Technical specification
| Product family | LNS-MS Series — tanker loading metering skids |
|---|---|
| Model | LNS-MS-LPG — Liquid Petroleum Gas |
| Metering principle | Coriolis mass flowmeter preferred where applicable |
| Flow range | Project-specific; meter and line size selected from min / normal / max loading rate |
| Line size / design pressure / design temperature | Project-specific |
| Measurement outputs | Mass flow, mass total; volumetric/density/temperature outputs where supported |
| Meter accuracy / repeatability | Vendor/model/project-specific; custody-transfer configuration where required |
| Pressure drop | Calculated for complete skid at minimum/normal/maximum flow and product viscosity |
| Process connection | ASME / EN / project flange standard |
| Piping material | Carbon steel / stainless steel / cryogenic stainless steel / project-specific |
| Skid frame | Structural steel base frame with lifting points; finish per project coating spec |
| Hazardous area | ATEX / IECEx / NEC / local requirement as specified by project |
| Instrument air | Required where pneumatic FCV or pneumatic actuators are selected |
| Communication | Modbus RTU/TCP, Ethernet, pulse, frequency, analog/digital I/O as selected |
| Control interface | Standalone batch controller, PLC/TAS/SCADA integrated, or hybrid |
Selection note: Coriolis is preferred, not automatically mandatory. Final meter selection accounts for flow range, viscosity, pressure drop, line size, custody requirements, product temperature and two-phase/flash behaviour.
Scope of supply
Trip/shutdown — typical: ESD command closes the batch/ESD valve and stops pump demand; grounding loss during tanker loading triggers controlled or immediate shutdown per project safety philosophy; overfill trip stops the batch and closes transfer valve(s).
