A cost analysis that can save you money

Compressed air is an expensive energy
The creation of compressed air is a cost-intensive process. It will therefore pay you to optimize the compressed-air networks. The first step is the knowledge how and where the optimization can be made. When considering the losses in a compressed-air system, the leaks in the system reach a percentage of about 42% of the total loss. Other important aspects are the design of the system and the control.

Calculation example
In a production plant of an average size (approx. 250 employees), a compressed-air network with a compressor power of 960 m³/h is installed. The compressor has a power consumption of 100 kWh and an operating time of 80%. The system runs 16 hours a day (2 shifts) and 276 days per year.

The first step to save costs
The basis for the system optimization is the precise and continuous analysis of the compressed-air system's actual consumption. To calculate this, the operator must know the actual volume flows of the system, the distribution of the compressed air in the network and, finally, also the volume flows during the idle periods – the leakage quantities. This data will help you to plan the optimization measures which have to be taken. The solution is: the use of volume flow sensors. They measure all the required data such as leakage quantities, consumption and distribution to the individual consumers (for a unambiguous cost allocation). This may help to adjust the maintenance intervals to the actual status of the system.

Consumption of process gases
In many production processes, not only compressed air but also other gases are used. These can be shielding gases such as CO2, helium or argon. In combustion processes, the fuel gas quantity is relevant. The use of an accurate and pressure-resistant volume flow sensor is the optimum solution for these applications in order to save costs and to guarantee a safe process sequence.

The measuring factors
Easy measurement with the SCHMIDT® Flow Sensor SS 20.261
The accurate volume flow measurement in compressed-air systems is used to
· save energy and increase the energy efficiency by a continuous leakage detection and an optimum compressor control
· calculation of compressed-air consumption and contracting
· system monitoring to avoid production downtimes and to guarantee a cost-effective and status-oriented maintenance

Measuring other gases?
For a lot of industrial areas, the detection of the different gas quantities is interesting since the cost minimization is not only important for the compressed air.

In many areas, the consumption has to be controlled and leakages must be detected, for example:
· production of electronic components
· application of shielding gases
· drying processes with inert gases and others
