The solution to web-enabled meter proving and flow meter calibration
All meters need to be proved regularly to ensure that they are operating within specified limits and comply with the Pipeline and Sales Agreements in operation. Flow computers perform rudimentary checks on the K factor / meter factor but the API Chapter 4.1 (Metering Systems Hierarchy of Proving Systems) calls for more stringent tests than the flow computer alone can provide. Furthermore, the prove data recorded has often been limited in scope, relying either on the basic prove reports generated by the flow computer or the use of nonstandard, unvalidated spreadsheets.
Approve™ is a web-based tool designed to effortlessly manage all the prove data generated by flow computers. The prove results from every prove performed are stored in a centralised database, creating a comprehensive and accurate prove history. This prove data can be shared instantly and securely across an entire corporate intranet or over the Internet, enabling technicians, auditors, operations and management to monitor the performance of every meter on the system.
Developed in conjunction with METCO, Approve™ is fully compliant with the specifications defined in API chapter 13.2 (Statistical Methods of Evaluating Meter Proving Data) for evaluating the performance of turbine or displacement meters in custody transfer and non-custody transfer metering applications.
To achieve this, Approve™ runs a series of tests on every prove and presents the outcome as a simple pass or fail; and providing expert advice on the next steps should a prove fail its tests.
Approve™ helps visualise the performance of every meter by presenting the prove data as a series of high quality control charts. These charts can be used to demonstrate the results of each prove to quickly identify those meters that need to be re-calibrated or replaced.
By simplifying the process of recording prove data and verifying the prove results, Approve™ helps ensure that all flow meters are providing accurate measurements at all times in accordance with industry best practice; whilst easily demonstrating compliance to auditors and other interested parties.
