Compressed air is the universal workhorse for many industries. It is easy to produce, transport, and is safe to handle; plus it can be utilized to drive a large variety of machines and tools.
But there is also a major downside with compressed air – it is also the least efficient form of energy in terms of electric power consumption at the compressor vs actual effective usage in the consumer’s process.

When it comes to improving efficiency and reducing energy costs, compressed air systems thus have the biggest potential for improvement. Within a compressed air system reducing leakages yields the largest benefit.

The first step to efficiency is measuring

To improve a systems efficiency, knowing about the media flow, and thus energy flow, is mandatory. By setting up comprehensive flow monitoring, compressed air system operators can easily observe production, distribution, and consumption throughout the company’s production areas.

Most notably, a precise and low-flow capable monitoring system permits tracking down of leakage rates, by analysing off-hour flow rates.

The better technology - non-invasive Ultrasonic Flow Meter

Monitoring compressed air systems is of course not a new or unknown topic for most companies. But many users struggle with the limitations and downsides of conventional compressed air meters.

Accuracy, stability against long term drift, robustness against humidity and dirt and immunity to pressure variation are some of the meter attributes that are needed to ensure useful balancing.

FLEXIM provides the best possible technical solution for this task by means of the FLUXUS G721 CA transit time measuring principle.

Make it flexible and economic – the portable compressed air meter

To make identifying potentials savings even easier, FLEXIM provides the perfect solution for portable and flexible compressed air metering – the FLUXUS G601 CA. This multi-tool is designed to be the all-around meter for energy managers and is capable of measuring compressed air and other gases, liquid and even thermal energy flows.

This meter, combined with an already existing monitoring system, provides the required data for leak analysis and detection where a fixed meter installation would not be cost-effective. Indeed, once the meter’s work is completed in one branch of the system, it may easily be moved to another for further optimization.
