THEMIS-UNO EI6 (GSM/GPRS)
The themis®uno index provides features that go far beyond simple remote reading. Existing options (usage and blocking tariffs, load profiles, communication interval control, data logging, electronic temperature compensation, etc.) can be combined in a way that suits the needs of individual customers. A secure firmware update in the air ensures that the technology is protected from the future and can be updated as needed to meet new requirements.
themis®uno is available with GSM / GPRS WAN communication. This guarantees secure data exchange between different communication partners. The way of secure authentication and data integrity and user authorization is top notch. BK-G..ETe diaphragm gas meters with themis®uno index meet the requirements of the Italian specification UNI-TS 11291.
The integrated “Valve Ve” valve in the diaphragm gas meter enables remote connection and disconnection of the gas supply. This significantly reduces costs and manpower caused by local gas outages. To avoid gas leaks in an unsafe installation, a smart downstream installation test is performed before opening the valve.
The integrated electronic temperature conversion system allows the volume to be converted to the basic temperature even for household needs. The meter displays the converted volume on the screen and transmits it to the appropriate data collection system.
