The core advantages of the Skid-Mounted Metering System are factory prefabrication, high integration, rapid deployment, stable accuracy, and easy operation and maintenance. Compared with traditional on-site assembly of disassembled parts, it leads in all five dimensions: construction period, cost, quality, safety, and space.
I. Construction and Deployment Advantages
Extremely Short Duration: 90% of assembly and commissioning are completed within the factory; on-site work requires only foundation fixing, pipeline connection, and power/gas hookup, reducing the installation cycle by 70%–80%.
Parallel Construction: Factory prefabrication proceeds simultaneously with on-site civil engineering, potentially shortening the overall project cycle by over 50%.
Minimal Footprint: Featuring a compact, modular layout, the system occupies only 40%–60% of the land area required by traditional solutions, making it ideal for confined station sites, mountainous regions, and offshore platforms.
Convenient Transport: Designed as a complete skid unit, it can be transported via road, rail, or sea, making it suitable for remote, international, and emergency projects.
II. Metering Accuracy and Reliability
Stable Accuracy: Flowmeter calibration, temperature/pressure compensation, pipeline purging, and leak testing are all performed within the factory, resulting in metering accuracy consistency far superior to that of on-site assemblies.
Multiple verifications: can integrate online calibration, multi-table comparison, and chromatographic analysis, supporting trade-transfer level accuracy.
Controllable quality: Standardized welding, flaw detection, and corrosion prevention in the factory reduce leakage points by 70% and lower failure rate.
Adaptability to Harsh Environments: Features temperature-resistant, pressure-resistant, anti-corrosive, and explosion-proof designs, enabling reliable operation in environments characterized by high sulfur content, high humidity, extreme cold, and high dust levels.
III. Functional Integration and Intelligentization Multifunctional Integration: Integrates filtration, pressure regulation, metering, shut-off, venting, heating, odorization, analysis, control, and alarm functions into one unit.
Fully Automated Operation: Utilizes a PLC and flow computer system for real-time data acquisition, temperature/pressure compensation, cumulative calculation, remote data uploading, and anomaly-triggered interlocks.
Remote monitoring: Supports SCADA/DCS integration, unattended operation, remote diagnostics, and data cloud platform.
Safety Interlocks: Features automatic shut-off and emergency venting mechanisms in response to overpressure, underpressure, leaks, or fire incidents, ensuring a high level of intrinsic safety. IV. Investment and O&M Costs
Cost-Effective Investment:Reduces on-site labor, material, machinery, and management expenses, lowering overall project costs by 15%–30%.
Simplified O&M:Features a single point of responsibility, integrated maintenance, and modular replacement, reducing downtime by 60%.
Online Maintenance:Enables online calibration, filter element replacement, and valve servicing without interrupting gas flow, ensuring continuous supply.
Extended Lifespan: Combines factory-applied anti-corrosion treatments with high-quality materials to extend service life by over 30%.
V. Flexibility and Scalability
Highly Customizable:Tailored designs based on specific flow rates, pressures, media types, functional requirements, and explosion-proof ratings.
Relocatable and Reusable:Upon project completion, the entire skid can be hoisted and relocated for reuse-ideal for pilot production, temporary gas supply, and emergency response projects.
Rapid Expansion: Features reserved interfaces to facilitate easy expansion via the addition of new branch lines or functional modules.
VI. Applicable Scenarios
Natural gas long-distance transmission pipeline distribution stations, city gate stations, and pressure regulating stations.
Oilfield single-well/multi-well metering, and oil-gas-water three-phase metering.
LNG/CNG refueling stations, urban gas distribution networks, and industrial furnaces.
Chemical plants, power stations, mining sites, offshore platforms, and remote regions.
Custody transfer, cost accounting, carbon metering, and smart pipeline networks.
Summary:The integrated metering skid represents a modular revolution in the field of fluid metering. By replacing traditional on-site assembly of loose components with a workflow of "factory fabrication, integrated transport, rapid installation, and intelligent management," it delivers superior lifecycle value that is faster, more accurate, more cost-effective, more stable, and safer.
