The generation of compressed air is a cost-intensive process. Therefore it is worthwhile to optimize compressed air networks.
The precise and continuous analysis of the actual consumption of a compressed air system is the basis for its optimization. To this end, the operator must know the actual volume flows of the system, the distribution of compressed air in the network and ultimately also the volume flows during idle times - the leakage quantity. This data can be used to determine exactly where and which optimisation measures must be carried out.
The solution is the use of volume flow sensors.
All necessary data will be collected, like leakage rates, consumption and distribution to the various points of use (cost allocation). Thus the maintenance intervals can be also flexibly adapted to the actual system states.
