PSIrwin is our system for the revision of large gas measuring systems. The aim of device revision is to regularly check the accuracy of all billing related gas measuring instruments. This has to be done in order to minimise measurement errors and the associated commercial risks.
Standardized procedures are the prerequisite for reproducible test results, which have to be agreed upon by all parties involved. Because of the complex structure of gas measuring stations various individual tests may have to be carried out simultaneously. The revision and maintenance of measuring devices/stations at different locations entails special requirements of scheduling and coordination of appointments. Only if all measured values are documented completely, evaluations can lead to the recognition of long-term trends.
The system not only supports revision, but also calibration and on-site tests. All relevant data is collected, saved and referred to in the process of calculating the results. The concept of the system ensures that the routine tasks that have to be carried out on-site are supported as efficiently as possible:
