Pressure-driven pumpless odorant injection for high-pressure natural gas pipelines
The patented Welker PulseInject™ is a pumpless, pressure-driven odorant injection system designed for proportional-to-flow natural gas odorization in city gate stations, transmission pipelines, compressor stations, power plants, peaking facilities, and high-pressure applications. Built for flow rates from 25 Mscfh up to 8 MMscfh and pipeline pressures up to 1480 psig, PulseInject™ automatically adjusts injection volume and rate to changing flow conditions. With few moving parts, low pressure differential requirements, Modbus or Ethernet communication, microSD audit trail logging, odorant and pneumatic supply filtration, redundant solenoids, and 110% containment, PulseInject™ supports dependable odorization with reduced maintenance and improved system visibility.
