Abstract (en)
[origin: WO2019140183A1] A gas meter is outfit with near field communication (NFC) devices for in-situ exchange of data. The NFC devices reside in separate compartments. A first compartment houses electronics necessary to generate values for volumetric flow of material in a pipe. The gas meter includes a second compartment with an access point that allows data, including telemetry data, to transmit from the gas meter to a remote device. In operation, the NFC devices exchange data between the first compartment and the second compartment, often through a wall or barrier that prevents flow of fluid between the compartments.
