SGD Inc. (www.sgd.com) introduced a computercontrolled changeover manifold that is designed to be used in a variety of configurations. The manifold can be set up with any gas supply on either side, with liquid container on one side and high pressure cylinders on the other side, or with liquid containers on both sides. A keypad is used to change operating parameters. The manifold has either brass or stainless steel gas components to suit the application. Features include digital pressure readouts for inlet pressures and outlet delivery pressure, built-in alarms, and replay contacts to activate auxiliary equipment such as remote alarms.
