PlatformsEmerson mass flow meters, GE iFIX, PID control, RTU link to pipeline SCADA
The brief
GAIL supplies LPG to customers along the Jamnagar to Loni pipeline from several metering stations. Nasirabad, near Ajmer, is one of the major metering and booster stations, where GAIL hands over LPG to HPCL and BPCL. The station needed its metering, control and reporting automated and linked to the pipeline's central SCADA.
What we built
Six Emerson mass flow meters connected to GE iFIX for continuous monitoring and reports, PID control of pressure and temperature from the same system, and every parameter relayed through GAIL's RTU to the central pipeline SCADA at Jamnagar. Supplied, installed and commissioned by us.
Metering
Six Emerson mass flow meters measure the LPG handed over at the station. iFIX monitors them continuously and produces the reports both sides rely on.
Control
Pressure and temperature are controlled by PID loops in the same system, so metering and control run from one operator station.
Part of the pipeline
Everything monitored and recorded locally is relayed through GAIL's RTU to the central SCADA at Jamnagar for overall pipeline monitoring.
Our scope
We supplied, installed and commissioned the complete system.
