Abstract: A flow meter having a housing with an inlet, an outlet and a cylindrical housing chamber fluidly connected in series between the inlet and the outlet. A cylindrical rotor is rotatably mounted within the housing chamber about an axis which is eccentric with respect to the axis of the housing chamber. In addition, a plurality of circumferentially spaced vanes are radially slidably mounted within the rotor. These vanes are urged radially outwardly into sealing contact with a housing wall which defines the housing chamber. A fluid working chamber is formed between each pair of vanes, the outer periphery of the rotor and the housing wall and this working chamber increases in size from the housing inlet and to the housing outlet. In operation, fluid flow into the housing inlet rotatably drives the rotor until the fluid is exhausted through the housing outlet. A detector detects the speed of rotation of the rotor thereby providing an indication of the fluid flow rate through the flow meter.

Abstract: An indicator for the rate of volumetric fluid flow includes a housing having a fluid passageway therein and a rotor contained in the housing in a position so as to be rotated by fluid flowing through said passageway. The indicator also includes a Hall effect transducer positioned outside the housing, responsive to the rotation of the rotor. The transducer produces an output signal corresponding to the rate of rotation of the rotor, and thus to the rate of fluid flow through the housing passageway. Preferably, the rotor is a paddle wheel disposed on an axle in the housing. The axle and thus the paddle wheel are retained in the housing by entrapment against a removable housing cover. The housing is otherwise mechanically imperforate to any connection between the rotor and the transducer.

Abstract: An automatic shut-off device for interrupting flow to a remote system in response to a flow fault associated with the remote system. The device generally includes a flow detection assembly, which senses the fluid flow through the remote system, and a fault detection assembly, which detects an interruption in the flow associated with the remote system and accordingly shuts-off fluid flow through the flow detection assembly. The flow and fault detection assemblies are remotely housed yet are mechanically connected by a common valve stem which connects the fault valve assembly with the flow interruption assembly. A metering assembly disposed in the flow detection assembly is responsive to the fluid flow and provides a visual indication of the flow rate through the system. Also provided are means for manually resetting the device in order to provide fluid flow upon correction of the fault.
