FLUXUS® G704 Compressed Air

The FLUXUS® G704 CA is a non-invasive flow meter for compressed air flow metering.

Compressed air is a very expensive form of energy and it is vital to measure and manage it as efficiently and accurately as possible. Accurate volume-flow measurement indicates the amount of compressed air lost as a result of leaks – an important economic factor, as every third compressor is operated only to compensate for air losses.

FLEXIM’s non-invasive clamp-on ultrasonic technology enables it to measure compressed air flow rates even at very low pressures (down to 3bar on steel lines and atmospheric pressure on plastic lines). For this reason, the FLUXUS® G704 CA is particularly suitable for non-invasively measuring quantities drawn off at individual points.

Benefits of the FLUXUS® G704 CA:

  • Virtually maintenance-free.
  • Highly accurate due to paired, temperature-compensating and traceable calibrated ultrasonic transducers.
  • Extremely high measuring dynamics: from the lowest to the highest flow velocities.
  • Simple, cost-effective retrofitting without any disruption to supply and pipe works.
  • No risk of leakage or pressure losses.
  • Bidirectional measurement: simple recognition of the flow direction.


Compressed Air Flowmeters

Measuring compressed air flows precisely in all conditions is the key to improving the energy efficiency of compressed air systems while reducing costs. Clamp-on technology means measurement takes place outside of the pipe wall,  which makes the FLUXUS CA range highly robust. This measurement principle reduces risk of compressed air contamination, and neither can the system cause potentials leaks. FLUXUS CA measures reliably at metal pipes down to 3bar (plastic pipes without limitation), is extremely sensitive to low flows down to 0,01 m/s and can be applied at pipes sizes from DN15 to DN250 FLUXUS CA permanent or portable meters are ideally suited for the following applications:
  • Conducting energy audits
  • Metering the consumption of compressed air
  • Checking existing meters
  • Detecting potential leaks
  • Balancing plant networks as well as monitoring compressor efficiency
