It is typically recommended to measure air flow and consumption at the following points in a compressed air system:
  • At the compressor outlet, to determine the amount of compressed air being produced.
  • At the point of use, to determine the amount of compressed air being consumed by each piece of equipment or process.
  • At the compressor inlet, to determine the amount of ambient air being drawn in by the compressor.
  • At the point of storage, to determine the amount of compressed air being stored in receivers or tanks.
  • At the point of distribution, to determine the amount of compressed air being distributed to different parts of the system.
  • It is also good practice to have a monitoring system in place to continuously measure and record the pressure, temperature and humidity of the compressed air at various points in the system.
