Reading and communication

Documentation mentions: Pulse output. These may be optional or specific to a variant.

Discovery tags come from the documented description, including optional capabilities. Confirm inclusion and exact size/configuration.

A connected metering system is five parts: meter → interface or module → network or gateway → software → billing, dashboard or control system. A quotation should name who supplies and maintains each one. AMR-ready equipment may still require separately quoted radio, gateway, head-end and billing software.
