More accurate data means more reliable revenue
Metering involves flow measurements, correction to standard conditions, flow/energy integration, and data transfer to the office domain for data storage and reporting. Further included may be functioned for meter-proving and calibration. Depending on the situation, the AML Metering system may be fully integrated with AML AMADAS and/or with AML Loading.
Metering requirements are subdivided as follows:
Class 1: Fiscal metering and sales
Class 2: Out of concession/ sales allocation
Class 3: Product allocations
Class 4: Environmental emissions.
For Class 1 fiscal metering, the system uses custody transfer approved flow computers. For all other classes and Class 1 backup, the heart of the metering function is a PC-based Flow Computer (PFC). The PFC consists of the flow calculation modules for the type of meter used by the application. Flow metering is performed using function blocks, each handling its pre-determined calculation, based on international standards (ISO, AGA).
