MGL SCADA System
❖ Advantages of dispenser connected on SCADA
Price change of all dispensers from one place simultaneously
Logging of totalizer helps in tackling dispenser jump related complaints
Accuracy of dispenser sale quantity
Consumption pattern analysis
Dispenser utilisation analysis
Shutdown of gas flow through dispenser in case of emergency (indirectly by activating cascade actuators)

❖ Upgraded system features
➢ New SCADA system will have capacity of 50,000 tags (approx. 500 CNG stations) and
can be scalable to 100,000 tags, upon requirement.
Features of New System:
Redundant and Replication Type Topology
02 Servers at MCC and the same set up will be replicated at SMCC. In the event of unavailability of MCC, system can be operated from SMCC.
Web Interface Users can access the system from any location using web server.
Data AnalyticsImproved Reports management as data received from sites can be corelated using arithmetic and logical functions.
Third Party Software Integration
SCADA system can be integrated with other systems such as SAP, PMAC software of DRS and IVMS etc.
MGL SCADA System
❖ SCADA Operated Valve
➢ Installed the Actuators on Valve for isolation of main gas line at Ghansoli.
➢ The Actuator are powered from pipeline Natural gas and are operated through SCADA.
➢ Modes of operation:
▪ Remote operation through SCADA
▪ Operation through Local Panel
▪ Operation through Manual Lever
▪ Operation through Manual Hand Pump

AUTOMATIC METER READING
❖ Benefits of AMR system
100% meter reading for every customer
Meter Reading on pre-defined time
100% Elimination of assessed bills
Billing of customers as per company requirements, leading to better and advance cash flow
Accurate reconciliation of meter readings between DRS and end customers
Analysis of Consumption pattern
Elimination of Manual errors
AMR System
❖ Additional features of AMR
• Pre-paid facility
➢ These meters can be installed for temporary connections wherein in customers can pay the gas charges in advance and obtain supply for short period of use.
• Disconnection of gas supply remotely
➢ These meters also have in-built valves.
➢ The valves can be operated from server end and stop the supply.
➢ The facility can be used to cut-off the supply of default customers.
