Clearing the Air

Reduce methane emissions with Welker’s proven technology! The design of the Accu/Line™ Zero Emissions includes all the key features of the Accu/Line™ family of smart odorant injection systems but eliminates the use of pipeline gas as the instrument supply, meaning no natural gas is released during normal operation.

This Accu/Line™ is a turnkey odorant injection system designed to inject liquid odorant proportional to flow into natural gas pipelines with flow rates from 10 Mscfh up to 70 MMscfh.

Environmentally Friendly Operation

Zero Emissions

The Welker EHUC Electro-hydraulic Unit serves as the system supply source, reliably actuating the odorant pumps. A single EHUC is powerful enough to support rapid injection rates for high-volume applications or periods of high demand.

Go With the Flow

Capability

The intuitive touch screen controller is the brains of the operation. Receiving feedback from the customer gas flow meter and system odorant flow meter, the controller adjusts the injection rate to changing flow conditions, ensuring continuous proportional to flow odorization. Measuring every pump stroke volume to an accuracy of 0.002 cc, the system odorant flow meter guarantees precise odorant injection.

In the Know

Real-Time Communication

Monitor and troubleshoot the Accu/Line™ on-site at the touch screen controller or remotely via Modbus to ensure optimal system performance. Access time- and date-stamped historical records saved to the installed microSD card for accurate reporting, planning, and scheduling.

For the Long Haul

Endurance

Improve system responsiveness to variations in flow rate with two odorant injection pumps of different volumes, or limit interruptions to operation with identical redundant pumps. The Welker F-9 Filter and Welker Original F-5 Filter Dryer prolong the operational life and reliability of the pumps by removing contaminants from the odorant and pneumatic supplies.

Size Matters

Capacity

From 5 gallons to 10,000 gallons, the odorant supply tank can be sized to suit a broad range of flow rates. Regardless of volume, each tank comes with 110% containment
