THEMIS-PLUS

Smart electronic index themisplus for commercial and industrial membrane gas meters
(BK-G10 – G40) is capable of directly delivering cumulative quantities using an integrated volume conversion device (temperature and pressure compensation). The combination of existing options (time and load dependent tariffs, load profiles, communication interval control, data logging, etc.) allows the index to be adjusted according to the needs of individual customers.

A GSM / GPRS communication module is available for them. This is in line with the requirements of the Italian standard UNI TS 11291, ensures the authenticity and integrity of data transmitted between communication partners, and also allows the approval of users. Secure, remote-controlled software updates and a modular principle ensure that the technology is secure in the future, and that it can be adapted as needed to respond retrospectively to new challenges at a low cost.

The indexes are delivered ready-made, which significantly reduces installation work.

Local communication

  • Optical bidirectional IEC 62056-21 connector (DLMS / COSEM)
  • Low frequency pulse output (Umax 10 V DC, Imax 100 mA, Fmax 4 Hz, min. Pulse width 125 ms)

Wide network communication modules

  • GSM / GPRS to DLMS / COSEM
  • GSM / GPRS to UMI
  • External antenna (optional)
The themisplus index provides secure end-to-end data encryption using current industry standards. This guarantees a reasonable level of data security and data protection. He is also very well protected from attempted fraud and unauthorized conduct and is able to report attempted unauthorized treatment to lower authorities. Remotely readable event logs therefore provide additional security. Certificate-based asymmetric encryption methods as well as symmetric encryption standards (eg AES-128) for existing communication modules are supported.
