Capability

Go With the Flow

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.

Real-Time Communication

In the Know

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.

Endurance

For the Long Haul

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 F-5 Filter Dryer prolong the operational life and reliability of the pumps by removing contaminants from the odorant and pneumatic supplies.

Capacity

Size Matters

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 sloped to the drain to protect against contamination and ease clean up.
