| Objectives | This project aims deliver an uncertainty tool for turbine and ultrasonic meters. If successful, the technique will allow error and bias to be monitored against MPE (maximum permissible error) and MPB (maximum permissible bias), to avoid costly annual re-calibrations where these are demonstrated to be unnecessary. | |
| Abstract | The cost of springing, recalibrating off-site and re-instating a typical ultrasonic meter is £25-30k (including cranes, transport and calibration charge). This cost is getting close to the cost of a new ultrasonic meter, so the ‘fit and forget’ concept and associated cost benefit advantage of selecting an ultrasonic meter could easily disappear unless something is done to improve confidence in longer calibration intervals (e. g. 2 -4 years, instead of 12 months). This project seeks to reduce the frequency of the above recalibration cost for installed ultrasonic meters and turbine meters, by increased confidence in the meter accuracy. Initially a prototype model was developed for calculating the maximum permissible bias (MPB), maximum permissible error (MPE) and uncertainty in volume and energy of flange-tapped orifice plate meters. Work proposed under this project looks to develop the tool further for turbine and ultrasonic meter technologies. The method to develop the uncertainty & error calculation tool for turbine and ultrasonic meters is as follows: Develop uncertainty and error calculation tool for turbine and ultrasonic meters Draft functional design specification for turbine and ultrasonic meters Final functional design specification for turbine and ultrasonic meters Review by technical expert of turbine and ultrasonic meter tool User acceptance tests and training By extending the improvement in the calculation of uncertainty, error and bias of volume and energy to cover turbine and ultrasonic meters (as well as orifice plate meters), the tool will allow National Grid to: Identify, where necessary, where site improvements can be most effective Demonstrate to Ofgem, third parties and external auditors that the metering is fit for purpose Ensure compliance with contractual obligations Separate uncertainties and errors as required by OIML (Organisation Internationale de Métrologie Légale)Enable the updating of National Grid policy and procedure documents Re-assess the tolerances of primary and secondary instrumentation during validationNote : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above | |
