CNG dispensers communicate with the central control system through wired or wireless protocols, including RS485, TCP/IP, MODBUS, or Ethernet-based networks. These connections allow the station to monitor performance and manage transactions.
The dispenser continuously sends information such as gas mass, pressure, temperature, and error codes to the control center. This data is used for diagnostics, reporting, and fueling authorization.
Real-time communication helps station operators detect issues early, optimize fueling cycles, and maintain consistent operation across all dispensers within the station.
