requirements and specifications that are not listed in this manual.
1.2 Product Description
The Welker OdorEyes
ECOsystem™ Pulse Bypass System With XLt Controller
is designed to infuse the customer pipeline proportional
to flow with natural gas that has been supersaturated with vaporized odorant. This skid-mounted automatic bypass system has
three (3) primary components: the touch screen controller, the valve section, and the odorant supply tank. Each primary
component plays an integral role in the operation of the ECOsystem™ and can be customized to better suit each application.
The touch screen controller serves as the system’s brain. It continuously receives feedback from the customer’s gas flow meter
and the flow switch in the valve section, allowing the system to respond to changing flow conditions. As pipeline conditions
change, the controller increases or decreases the injection rate so that the ECOsystem™ continues infusing proportional to flow.
On-site and remote troubleshooting and monitoring are made easier by time- and date-stamped audit data detailing system
performance, alarm history, and odorant tank level. An optional solar panel generates renewable energy to power the system
when an electrical source is unavailable.
The valve section contains one (1), two (2), or three (3) solenoids, which control the flow of gas through the odorant supply tank
and into the pipeline. Having two (2) or three (3) solenoids allows the ECOsystem™ to better respond to and accommodate
varying flow rates and limits interruption to operation in the event of solenoid maintenance. To prolong the operational life of the
regulator and solenoid(s), the Welker F-5 Filter Dryer conditions the natural gas supply. The flow switch communicates the
solenoid operation to the controller to ensure proper odorization. For pulse bypass systems used in cold climates, a heater with
thermostat can be added to replenish heat lost during regulation.
Each odorant supply tank is equipped with a tank fill inlet, vent port, blanket pressure inlet, level gauge, and outlet to the pipeline.
The temperature transmitter communicates odorant temperature to the controller so the system can compensate for
temperature changes within the odorant tank. For added automation, an electronic level transmitter can be installed to
communicate tank level to the controller. Regardless of volume or orientation, the odorant supply tank comes with 110%
containment that is sloped to the drain for easy draining.
Welker may custom design the ECOsystem™ Pulse Bypass System With XLt Controller to suit the particular application and specifications
of each customer.
1.3 Safety Warning
Wherever hazardous gases or vapor-producing liquids are used, transported, or stored, the potential for an accidental leak exists.
Continuous monitoring of these hazards is essential to ensure personnel safety.
