Project Synopsis

Automation system for Compressed Natural Gas Compressor. This is used for retail auto gas outlets. The system is built in a flameproof cabinet and has a redundant CPU system. HMI operation is done using inputs of external keys to PLC, mounted on the flameproof Panel. Online data, trends, alarms etc can be seen on SCADA. Inlet gas flow and Discharge gas flow is provided on HMI as well as SCADA for observation. The flow meter communicates with PLC using Modbus RTU Protocol.

The scope of work included :

  • Design & supply of control systems.
  • Software development
  • Commissioning
