Welker Tanker Odorizer
Odorant Injection

The purpose of this injector is to provide a safe and efficient method for odorizing tank cars.  By depressing the "fill" button, ororant is drawn into the injector, and an equal volume of red oil is displaced into the level indicator.  When the correct amount of oil is drawn in, release the button on the fill valve.  The ororant will be injected into the tank car when the "inject" button is pushed and held in the depressed position until the oil level returns to its lowest level.  The injector should always be left in the last mentioned position between uses.
