System calibration & validation for metering control systems
KROHNE certified validation with full audit trail
- Additional diagnostics and monitoring to achieve full performance of the system
- Verification of the correct firmware and software versions and parameter settings
- Alarm and error log review
- Periodical inspection, including environmental and metrological certification
During the validation of a metering control system, a KROHNE engineer will verify, amongst other items, whether all components are still sealed as per metrology requirements, that parameter settings have not changed, and that firm- and hardware versions are still as per certification. Also, event and alarm logs will be reviewed and any necessary corrective actions defined.
Usually validations are combined with a maintenance visit where analogue inputs are re-calibrated and data communication is tested, filters are cleaned or replaced and operational items such as CPU loadings are analysed.
Product highlights
- Periodical validation of instrument seals, parameter settings and firmware and software versions
- Review of alarm and event log with implementation of corrective actions where required
