تعیین فواصل کالیبراسیون مطلوب با تعادل مواجهه مالی با مصارف اندازه گیری

The case study of the ultrasonic flow meters, operating in the custody-transfer gas flow measurement system, are used to illustrate the calculation algorithm. It has been shown that the determination of calibration intervals is a complex mathematical and statistical process requiring accurate and sufficient data including calibration results and registered costs. Application of the suggested calculation algorithm can be beneficial in assessment and minimisation of financial risks associated with currently implemented maintenance strategies as well as in review of calibration intervals to balance financial exposure and measurement costs.
