Accu/Line™ Solar

Solar-powered, zero-emission odorization for remote natural gas pipelines

The Welker Accu/Line™ Solar is a solar-powered natural gas odorizer designed for zero-emission odorant injection in low-flow, low-energy, and hard-to-reach pipeline locations. This turnkey odorization system injects liquid odorant proportional to flow into natural gas transmission and distribution lines from 10 Mscfh to 250 Mscfh, helping operators maintain accurate odorization while reducing methane emissions. With electric injection control, remote monitoring via Modbus or Ethernet, self vapor purge, audit trail logging, and redundant pumps with automatic failover, the Accu/Line™ Solar delivers reliable odorant delivery for remote pipeline odorization and ESG-focused operations.

Where to Use
Natural Gas Odorization Solar-powered odorant injection for low-flow natural gas transmission and distribution lines in remote or low-energy locations.
Chemical Injection Injects liquid odorant proportional to flow for dependable pipeline odorization and controlled chemical delivery.
Emissions Reduction Supports zero-emission odorization by eliminating methane release to the atmosphere during normal operation.
Remote Monitoring Designed for hard-to-reach pipeline sites where off-site visibility, troubleshooting, and system reporting are needed.

Solar Power

Uses solar energy to support reliable odorization in low-flow, low-energy, or remote pipeline environments where traditional power may be limited.

Zero Emissions Design

Helps reduce methane emissions by preventing methane release to the atmosphere during normal odorization operations.

Electric Injection Control

Automatically adjusts odorant injection proportional to changing natural gas flow conditions, helping maintain accurate and consistent odorization.

Remote Monitoring Using Modbus or Ethernet

Enables off-site monitoring and troubleshooting, giving operators better visibility into system performance without frequent site visits.

Self Vapor Purge

Helps eliminate vapor lock so the system can maintain dependable odorant delivery and reduce interruptions in injection performance.

Audit Trail and Alarms Log Backed Up on microSD Card

Stores time- and date-stamped system records to support reporting, maintenance planning, alarm review, and operational accountability.

Redundant Pumps With Automatic Failover

Provides backup injection capability by automatically switching pumps when needed, helping limit downtime and maintain continuous odorization.
