Problems solved by technology

Due to the elongated rectangular configuration of conventional rotameters, an increase in valve size results in an increase in the cross-section of the rotameter body, not just in the area of ​​the valve, but along its entire length

Embodiment Construction

[0055] see Figure 1-3 , devices for measuring and metering fluid flow include rotameters. The rotameter 10 includes a rotameter body 20 having an inlet 22, one or more outlets 24, and a flow tube 26 extending between the inlet and the outlet. Flow tube 26 has a tapered conical configuration and is configured with its narrow end 30 located adjacent or near outlet 22 and its wide end 32 located adjacent or near outlet 24 . At the inlet end, the body 20 includes a valve cavity 100 positioned between the inlet 22 and the flow tube 26 and enabling fluid communication between the inlet and the flow tube. In use, the rotameter 10 is arranged to be oriented vertically so that the inlet 22 is at the bottom and the outlet 24 is at the top. Mounting holes 28 facilitate mounting rotameter 10 in this manner.

[0056] The inlet 22 and outlet 24 each have a cylindrical configuration with internal threads formed thereon. Ports 22 and 24 are adapted to receive threaded adapters 40 which m...

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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 62 / 099,701, filed January 5, 2015, the entire contents of which are hereby incorporated by reference. technical field [0003] The present disclosure relates to measurement and metering of fluid flow. More specifically, the present disclosure relates to a rotameter that includes an integrated valve. Background technique [0004] A rotameter is a variable area flow meter used to measure and control the flow of liquid through a conduit. Rotameters include flow tubes that have a tapered (eg, conical) configuration. Rotameters are mounted vertically with the narrow end of the tapered flow tube at the bottom and the wide end at the top. The rotameter is positioned in the fluid circuit such that the fluid flows through the flow tube from bottom to top. [0005] The fluid flow includes a non-buoyant indicator, such as a piston or pellet, located in the flo...
