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
