Compressed air is convenient but energy intensive. Pipeline optimization should reduce unnecessary pressure, detect abnormal consumption and maintain adequate pressure at critical users. Permanent flow, pressure, dew-point and power data turns leak surveys into a measurable improvement program.
Measurement architecture
| Area | Recommended measurement | Decision supported |
|---|---|---|
| Compressor outlet | Flow, pressure, temperature and electrical power | Specific power and compressor sequencing |
| Main header | Pressure and flow | Total demand and storage response |
| Production branch | Thermal mass or suitable gas flowmeter | Department allocation and leak trend |
| Critical point of use | Pressure transmitter | Minimum useful delivery pressure |
| Dryer outlet | Pressure dew-point transmitter | Air-quality and dryer performance |
Performance indicators
| KPI | Calculation or basis | Use |
|---|---|---|
| Specific power | Electrical kW / delivered flow | Compare compressors at stable conditions |
| Off-shift base load | Flow during no-production period | Leak and unauthorized-use indicator |
| Header pressure variation | Maximum minus minimum pressure | Storage and control stability |
| Branch consumption | Integrated standardized volume | Cost allocation and improvement tracking |
| Dew point | Pressure dew point at operating pressure | Dryer and air-quality verification |
Flowmeter selection
Confirm whether reported flow is actual or standardized volume. Record reference temperature and pressure, gas composition, pipe size, operating pressure, flow range, available straight run and expected moisture or oil carryover. Thermal mass meters are common for dry compressed air, while other technologies may be preferable for wet, high-pressure or large-diameter applications.
Optimization sequence
- Establish a seven-day flow and pressure baseline.
- Measure off-shift demand and isolate branches systematically.
- Repair leaks and verify savings from the same meter.
- Reduce header pressure only after confirming critical-user pressure.
- Optimize compressor sequencing and receiver storage.
- Track dew point and pressure drop across filters and dryers.
