Compressed-Air Cost in Air-Gauging Systems

Air-gauge cost depends on point-of-use flow and time, not only compressor power. A useful assessment measures active and idle states, simultaneous gauge operation and the plant’s validated cost per delivered air volume.

Engineering workflow

  1. Measure flow at representative pressure and operation.
  2. Separate active measurement time from idle flow.
  3. Use a plant-approved cost per 1,000 m³.
  4. Verify that any shut-off restores stable measurement conditions.

Worked example

A 25 L/min gauge running 16 hours/day for 300 days uses 7,200 m³/year. Ten identical simultaneous gauges use 72,000 m³/year before leakage and diversity adjustments.

Limitations and checks

  • Simple volume costing is not a compressor-system simulation.
  • Leakage, pressure drop and compressor part-load efficiency need site data.

Use the calculation as a screening input, then confirm the actual gauge, fixture, software or automation configuration.
