Assignee:

ROSEMOUNT INC. - Chanhassen MN

International Classification:

G01F 1/56

US Classification:

7386108

Abstract:

A magnetic flowmeter sensor includes two sensor faces, a conduit, a liner lining the conduit, and mechanical fasteners. The sensor faces are on each end of the sensor for connecting the sensor to the process fluid flow. The conduit connects the two sensor faces for conducting the process fluid flow through the sensor. The liner extends across at least a portion of each sensor face at each end of the flowmeter sensor to form a planar sealing surface on each end of the sensor. The liner includes holes through which the mechanical fasteners pass to mechanically attach the liner to the flowmeter sensor to prevent shifting of the liner. The mechanical fasteners do not extend beyond the planar sealing surfaces.

International Classification:

B01D 4610

US Classification:

553853, 55498, 55502, 123198 E

Abstract:

An underhood air cleaner ( ) for a vehicle ( ) has an inlet shroud seal ( ) self-mounted to the filter housing ( ) at the filter inlet ( ) and engaging the hood ( ) at the exit opening ( ) of the hood air channel ( ). The self-mounting is accomplished without extra parts or fasteners such as bolts and clamps. Both axial ( ) and radial ( ) retention is provided for the shroud seal ( ) on the filter housing ( ), as well as reduced inflow restriction.

International Classification:

G01F 1/58
G01F 15/00

Abstract:

A magnetic flowmeter for sensing process fluid flow includes a flow tube configured to receive the process fluid flow there through and a plurality of electrodes disposed to contact process fluid. At least one electromagnetic coil is disposed proximate the tube. A flow tube liner is provided in the flow tube having an interior surface configured to contact process fluid and an exterior surface mounted to the flow tube. The flow tube liner has at least one adhesion feature in the exterior surface which promotes adhesion between the flow tube liner and the flow tube. A method is also provided.

International Classification:

G01F 1/58
B29B 15/00

Abstract:

A polymeric flow tube assembly is provided. The flow tube assembly includes a flow conduit configured to allow fluid flow therethrough. A first coil is mounted with respect to the flow conduit and disposed about a first magnetic pole member. A second coil is mounted with respect to the flow conduit and is disposed about a second magnetic pole member. The second magnetic pole member is configured to cooperate with the first magnetic pole member to generate an electromagnetic field across a flow measurement aperture. First and second electrodes are positioned within the flow tube assembly to measure an electromotive force generated within a fluid in the flow measurement aperture. At least one of the first magnetic pole member, second magnetic pole member, first electrode and second electrode is formed, at least in part, of a polymer.

International Classification:

G01F 1/58

Abstract:

A magnetic flowmeter flowtube assembly includes a conduit with a first end and a second end. A first neck flange is coupled to the first end of the conduit and has an inside diameter with a first notch extending radially outwardly therefrom. A second neck flange is coupled to the second end and has an inside diameter with a second notch extending radially outwardly therefrom. A fluoropolymer liner is disposed within and extends through the first neck flange, the conduit and the second neck flange. A pair of electrodes is mounted relative to the liner to measure a voltage induced within a process fluid flowing through the liner. A first spring-energized seal ring is disposed in the first notch and a second spring-energized seal ring disposed in the second notch. A method of sealing a magnetic flowmeter having a fluoropolymer liner is also provided.
