The electronic index for Elster diaphragm gas meters

Currently in development: The electronic index for Elster diaphragm gas meters presents smart index technology suitable for the implementation of a fully-fledged smart metering system. It offers the possibility of querying historical data, displaying tariffs and switching an optionally integrated valve.
For a standard diaphragm gas meter, gas consumption is displayed as operating volume.
The electronic index is so designed that the metrological part is protected by the statutory calibration seal, while the communication technology and the batteries are sealed separately. In this way, it is possible to change the communication module or the batteries once the index has been fitted, without breaking the calibration seal.
