SCHMIDT® Flow Sensors for Compressed Air

For measurements in compressed air systems the thermic SCHMIDT® Flow Sensors provide many benefits:

  • Direct detection of norm flow velocity independent of pressure and temperature
  • For tube diameters DN 15 ... DN 1.000
  • Installation and removal during production and under pressure possible
  • Very high flow velocities up to 200 m/s (also for undersized tubes)
  • Very small measuring range limit of 0.2 m/s for detection of leakage

 

Which sensor is suitable for which application?
For measurements in compressed air systems either Insertion- or Inline-sensors can be used.

Application examples:

Accounting and contracting

  • Measurement of compressed air consumption

Saving of energy and efficiency through

  • Detection of leakages
  • Optimal compressor controlling

Plant and machine monitoring

  • Avoid production loss
  • Optimizing processes
  • Perform-conditioned maintenance
