• PSIrwin: Solution for technical inspection and calibration

PSIrwin is the unique fully integrated software system for regular inspection of measurement accuracy of all billing related energy measuring systems.

The system provides a choice of methods for reviewing all procedures of volume and gas quality measurements and an interface to invoicing (external system). In order to meet these complex requirements, many centralised and decentralised (notebook) functions are available in an integrated system environment.
Master data which is related to stations and devices is managed in a structured way either centralised or decentralised; data integrity is guaranteed by selected uploads and downloads. The operator carries out tests and prepares the revision reports and calibration protocols with user-friendly functions on-site. All necessary procedures for evaluating the tests are integrated in the system. Revision history and trend displays are also important features of the application.

If you would like to have more information about using PSIrwin for test stations, please do not hesitate to contact us.
