Welker’s patent pending pumpless, pressure-driven odorant injection system is a complete solution for proportional to flow odorization for flow rates from 25 Mscfh up to 8 MMscfh and pipelines with a maximum allowable operating pressure of 1480 psig.
Key Features
- Few moving parts
- Low pressure differential required for injection
- Programmable Logic Controller automatically adjusts the injection volume and rate to changing flow conditions
- Remote monitoring and communication using Modbus or Ethernet
- Audit trail and alarms log backed up to microSD card
- Welker F-9 Filter and Welker F-5 Filter Dryer remove contaminants from odorant and pneumatic supplies
- Low-pressure odorant supply tank with 110% containment sloped to drain
Key Benefits
- Reduced maintenance
- Reduced pneumatic supply pressure required compared to pump injection systems
- No manual injection volume adjustment
- Continuous proportional to flow odorization
- Off-site system monitoring and troubleshooting
- Time- and date-stamped historical records for accurate reporting, planning, and scheduling
- Contaminant removal prolongs operational life and reliability
- Skid containment protects the ground from contamination and ease clean up
- Identical redundant solenoids limit interruptions to operation
