Metering Function

Nitrogen distribution systems require accurate flow measurement for tracking consumption, allocating costs between departments or processes, and optimizing supply system efficiency. Metering skids measure volumetric or mass flow with pressure and temperature compensation converting to standard conditions. Typical accuracy ±1-2% meets industrial metering requirements for non-custody transfer applications.

System Components

Complete skids include thermal mass, vortex, or turbine flow meters based on flow range and accuracy needs, flow totalizer displaying cumulative volumes, pressure and temperature transmitters for compensation calculations, flow indicator with local display, isolation valves, optional pressure regulation, and instrumentation panel. Compact designs suit installation in nitrogen distribution headers.

Meter Technology

Thermal mass meters measure directly at actual conditions without pressure/temperature compensation. Vortex meters provide no-moving-parts reliability for clean nitrogen service. Turbine meters offer high accuracy for steady flows. ERGIL selects technology based on flow rate, required accuracy, and installation constraints with typical ranges 10-10,000 SCFM.

Applications

Facility nitrogen distribution monitoring consumption across departments, pipeline purging and testing operations tracking nitrogen usage, tank blanketing systems measuring inerting gas flow, instrument air backup monitoring, and any industrial nitrogen application requiring flow measurement. Serves manufacturing, chemical plants, refineries, food processing, and electronics facilities.

Control Integration

Flow data integration with facility monitoring systems enables consumption tracking and optimization. Totalizer outputs for billing and allocation purposes. Alarm functions for high/low flow conditions. Remote monitoring provides real-time usage visibility supporting nitrogen supply management and troubleshooting.
