March 2022 1.0 Overview The GPL 750 natural gas odorizer accurately doses the gas with odorant in individual droplets of 0.01 cc. The optical sensor counts each droplet and feeds the information back to the controller. The controller measures the flow and injects the next odorant dosage when sufficient gas has passed.
GPL 750 | Installation and Maintenance Manual March 2022 1.2 Odorant Filter The continuous mode provides a constant odorant flow into the stream at appropriate proportions. Use the continuous mode for gas flow rates higher than 100 MSCFH. 1.3 Pressure Regulator...
GPL 750 | Installation and Maintenance Manual March 2022 1.6 Optical Comparator The optical comparator and arrays use fiber Optical Comparator optics to count drops as they fall through the drip chamber and into the line. Even with tiny doses, the reliable counting of drops drives the injection system’s accuracy.
GPL 750 | Installation and Maintenance Manual March 2022 1.8 Drip Chamber and Optical Array The drip chamber incorporates the use of (2) optical arrays on either side of the chamber to count the odorant drops. There is a total of...
GPL 750 | Installation and Maintenance Manual March 2022 2.0 Principles of Operation The GPL 750 uses batch mode operation to odorize natural gas; the unit waits for a • predetermined amount of gas to flow through the pipeline meter before opening the solenoid valve and injecting the odorant.
"blow-back" tee and ball valve. The tubing exiting the bottom of the GPL 750 shall be no less than 45 degrees from the horizontal, and there should be no horizontal portions of tubing between the unit and the injection point. This positioning allows the drops to fall by gravity into the pipeline.
Precision flathead (jeweler’s) screwdriver 3.3 Tubing Once an appropriate location has been determined for the GPL 750 and the unit has been properly mounted, use Tubing Illustration on the following page to install the tubing per your company’s procedures and applicable code.

GPL 750 | Installation and Maintenance Manual March 2022 3.5 Leak Testing After installing the tubing and wiring, all the tubing and fittings connected to the system need to be leak tested. Pipeline pressure is slowly brought back to the bulk tank during leak testing.
GPL 750 | Installation and Maintenance Manual March 2022 3.6 Purging the Odorant Line 1. Configure odorant and gas flow settings (See GPL 750 User's Manual for further information). 2. Ensure that gas flow on the main screen of HMI reflects actual flow in the pipeline.
