Abstract
A rotameter includes a rotameter body including an inlet, an outlet, and a flow channel that provides fluid communication between the inlet and the outlet. A valve for controlling fluid flow through the inlet includes an actuator rotatable about a first axis. The actuator includes worm gear threads. The valve also includes a valve drive element rotatable about a second axis that extends transverse to the first axis. The valve drive element includes worm gear teeth that mate with the worm gear threads on the actuator so that rotation of the actuator about the first axis imparts rotation of the valve drive element about the second axis. The valve drive element further includes first screw threads that rotate with the valve drive element about the second axis. The first screw threads are configured and arranged to mate with and engage second screw threads to cause linear movement of a valve component along the second axis in response to rotation of the valve drive element. The linear movement of the valve component opens and closes the valve.
