PULSE BYPASS Odorization System
The PRECO Pulse ByPass Odorization System has been designed for lower volume and lower pressure applications and offers a cost-effective alternative to pump type injection systems.
PRECO Pulse ByPass Odorizer
The PRECO Pulse Bypass Odorizer uses 0 to 300 cubic inches of operating gas with the use of up to four pulse bottles. This unique design feature allows the customer to make field adjustments of bottle volume. The working volume of the pulse bottle may be tuned by changing the length of the adjusting rod.
Principal of Operation
The operating principle of ByPass Odorization is to use higher pressure gas supply from the transmission line to introduce odorant vapors into a lower pressure feeder or distribution line. This is accomplished by diverting or bypassing un-odorized natural gas through an odorant filled day tank to mix with odorant vapors. Odorization occurs when the odorant saturated bypass gas is returned to the down streamline. A signal from a flow computer or a meter switch is received by the PRECO Sentinel II Controller to actuate the pulse bottle solenoid valve. The controls can operate on 110 VAC or 12 VDC Solar.
In addition to the adjustable volume pulse bottle, the system includes a day tank with odorant level & temperature gauge, and a bulk tank all mounted on one easy to install modular base skid or as shown with a containment tub. This system provides odorization that tracks the flow of natural gas. The PRECO Odorizer can be powered by either 110 VAC or 12 VDC with a PRECO solar assembly.
The PRECO Controller is a Solid State Controller. It receives a normally open dry contact closure proportional to flow, from the customer’s gas line instruments or PRECO meter interface switch or a 4-20 Milliamp signal.
