This manual covers the installation, operation, maintenance, and safety procedures for the Welker ECOSYSTEM™ Pulse Bypass System used for odorant infusion.
The Welker ECOSYSTEM™ Pulse Bypass System is a skid-mounted automatic bypass system designed to infuse natural gas pipelines with vaporized odorant proportional to flow. The system consists of three primary components: the touch screen controller, the valve section, and the odorant supply tank. It features continuous feedback from gas flow meters and flow switches to adjust injection rates automatically.
The system is designed to infuse customer pipelines with natural gas that has been supersaturated with vaporized odorant.
The system supports AC 120 V, DC 12 V, and DC 24 V electrical connections.
For sample-exposed seals, use non-hydrocarbon-based lubricants like Krytox®, while non-sample-exposed seals can use non-hydrocarbon or silicone-based options such as Molykote® 111.
