Smart high-flow odorant injection for large natural gas pipeline systems
The Welker Accu/Line™ Hi is a natural gas injection odorization system designed for high-flow transmission pipelines, distribution pipelines, compressor stations, power plants, peaking facilities, municipalities, and renewable natural gas applications. Built for flow rates from 50 Mscfh up to 70 MMscfh and maximum operating pressure up to 1800 psig, the Accu/Line™ Hi automatically adjusts odorant injection rate to changing flow conditions for continuous proportional-to-flow odorization. With an intuitive touch screen controller, Modbus or Ethernet remote monitoring, microSD audit trail and alarm logging, redundant pumps with automatic failover, and self-priming pumps, the Accu/Line™ Hi supports reliable odorant delivery in demanding high-flow applications.
