The development of the smart meter has added a new dimension to correct measurement and billing using Watt-hour and gas meters: smart meter communication. In future, requirements in the approval process will also be set for the performance of this communication. Purchasers of Watt-hour and gas meters are already stipulating specific requirements in addition to the applicable regulations.
Smart meter communication
NMi currently incorporates additional requirements in the test plan for the type examination of smart meters. The communication features of the hardware can now be tested, for example, which includes examining how the Smart meter communication works and whether a connection is actually established. Data security can also be evaluated in accordance with WELMEC guide 7.2.
Besides the standard test procedure, NMi can integrate additional tests into the test plan arising from OIML recommendations, EN and IEC standards or customer-specific requirements. With regard to communications, this might be power line communication (PLC) and ZigBee communication. A great addition for your customers! A complete list of the additional tests is available on the application form (watt-hour meters / gas meters).
