Enectiva Gas SG Transmitter for gas flow meters ELSTER/PREMAGAS

Radio reading systems are widely used all around the world by gas network operators. The Enectiva SG radio module converts pulse output (read contact) to SIGFOX, which offers you a high-class communication, battery life, operating cost and wide area coverage. Furthermore, at low investment cost, it will increase you work efficiency and reduce error rate in case of manual readings of meters. Radio modules also allow you to closely monitor the customer’s consumption while maintaining their privacy and they signalize potential errors or unauthorized interventions. The transmitted data could be secured by encryption.

Recorded and transmitted data:

(regularly sent data are shown in bold print, the remaining data are sent sequentially)

• Gas meter serial number
• Status of the gas flow volume counter at the time of reading
• Current time
• Date of reading
• Records of monthly consumption for previous 12 months before the date of the current reading
• Consumption peak flows
• Battery operating time
• In case of a malfunction, the module sends the time when the malfunction was detected
• Warning messages:
  • Defect announcement (depends on firmware version).
  • Detection of presence of the radio module on the meter
  • Low battery - Battery voltage decrease
