*The following procedures have been written for use with standard Welker OdorEyes parts and equipment. Assemblies that have been modified may have additional
requirements and specifications that are not listed in this manual.
1.2 Produc Descrip ion
The Welker OdorEyes ECOsystem™ Pulse Bypass System With X t Controller is designed to in use the customer pipeline proportional
to low 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 o the ECOsystem™ and can be customized to better suit each application.
The touch screen controller serves as the system’s brain. It continuously receives eedback rom the customer’s gas low meter
and the low switch in the valve section, allowing the system to respond to changing low conditions. As pipeline conditions
change, the controller increases or decreases the injection rate so that the ECOsystem™ continues in using proportional to low.
On-site and remote troubleshooting and monitoring are made easier by time- and date-stamped audit data detailing system
per ormance, 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 low o 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 low rates and limits interruption to operation in the event o solenoid maintenance. To prolong the operational li e o the
regulator and solenoid(s), the Welker F-5 Filter Dryer conditions the natural gas supply. The low 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 ill 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 or
temperature changes within the odorant tank. For added automation, an electronic level transmitter can be installed to
communicate tank level to the controller. Regardless o volume or orientation, the odorant supply tank comes with 110%
containment that is sloped to the drain or easy draining.
Welker may custom design the ECOsystem™ Pulse Bypass System With X t Controller to suit the particular application and specifications
of each customer.
1.3 Safe y Warning
Wherever hazardous gases or vapor-producing liquids are used, transported, or stored, the potential or an accidental leak exists.
Continuous monitoring o these hazards is essential to ensure personnel sa ety.
