Operation & maintenance for provers and master meters
Support for site engineers in analysis of diagnostics and system maintenance
- Maintenance contracts and service level agreements
- Pre-defined service rates and response times
- 24/7 Customer support and emergency helpdesk
- Periodic health checks and software updates
Having so many calibration facilities in their manufacturing facilities, KROHNE has dedicated experienced engineers who are very familiar with the required verification and calibration actions, and the analysis of diagnostics. These engineers are available within a service contract, to advise the operators dealing with such facilities on diagnostic abnormalities, and regular maintenance actions, as well as assistance with software updates.
In addition KROHNE engineers can support on site in the periodic verification and re-calibration of provers and calibration facilities to ensure full traceability to the local national standards, according to an agreed schedule. The services can also be expanded to include master meter re-calibrations.
