Sourcing notes
Metering products are tightly regulated because they are used for billing. Confirm the destination’s metering standard, accuracy class, sealing requirement and the type-approval route before design freeze. Communication protocol and data security requirements also vary by utility.
Quality, compliance and documentation
Suppliers should provide type-test reports against the relevant IEC or national standard, accuracy calibration records and, where applicable, pattern approval certificates. For smart meters, request the interoperability test report and the firmware update policy.
How to inquire
Provide the meter type, accuracy class, communication requirement, target quantity and destination market. Type-approval support should be discussed at the first contact.
