The regulator is designed to allow automatic change-over when one cylinder becomes empty, allowing you to change cylinders without interruption of service to the gas appliance. Ideal for motor homes, RVs, and domestic installations because they maintain reliable uninterrupted service when using two cylinders. Remote indicators are available for some models to allow you to monitor the cylinder volume at distances up to 10 ft from the regulator.
