Stationary Ultrasonic Clamp-On System for Flow Measurement of Compressed Air and Other Industrial Gases

Compressed Air Flow Measurement

Compressed air is a costly source of energy due to its efficiency. For each joule of mechanical work performed with a pneumatic instrument, it takes approximately 20 times the electrical power to produce and store the air. However, despite this low yield, compressed air is indispensable in many industries due to its production-related advantages, which makes it all the more crucial that the compressed air's use is as efficient as possible.

Calculation of energy use is essential. By accurately detecting current air volume flow, a device's pneumatic components can be assessed cost-effectively by quickly and accurately identifying potential overloads (such as when air velocities are too high) or piping network malfunctions. The precise distribution of consumption proportions to individual output stages provides possibilities for fact-based, economic decisions. Moreover, the volume-flow calculation shows the amount of compressed air lost due to leaks – a significant financial consideration - as every third air compressor in place is only there to compensate for air losses.

The compressed air flow meter FLUXUS G721 CA from FLEXIM is the perfect solution. FLEXIM's non-invasive clamp-on ultrasonic technology is remarkable in that it works at low pressures (down to 3bar on steel lines and atmospheric pressure on plastic pipes).  The FLUXUS G721 CA reliably captures minimal flow rates, allowing the discovery of the smallest leaks.

Process Analytics by Inline Refractometry

Process refractometer

Refractometry - in other words, the measurement of light refraction - is a well-established method of choice for determining the concentration, density and purity of many liquids.

By measuring the refractive index directly within the process, PIOX® R allows for a highly accurate measurement, long term reliability and continuous quality management either in hygienic and ultra-clean sanitary or harsh industrial environments with high process pressures, temperatures and corrosive media.

Unlike other available measurement technologies, FLEXIM’s PIOX® R employs its patented transmitted light principle and thus never bears the risk of measurement drift and false readings from deposit build up at the prism.

The unrivaled design and the integrated diagnostic tools moreover allow for very cost effective and predictive maintenance intervals.


  • Patented transmitted light measurement principle - offers completely drift free, precise and long term stable measuring
  • No flow velocity needed - which is required from conventional technologies
  • Highly precise optical measurement technology offering laboratory accuracy in real-time
  • Measurement unaffected by gas bubbles and turbidity as well as the media‘s viscosity
  • Internal self-diagnostic tools for predictive and very cost effective maintenance efforts
