Patent number: 7930816Abstract: A method of manufacturing an electromagnetic flow meter assembly is disclosed. The method comprises forming an insert from a deformable material, forming at least one reinforcing component; arranging the reinforcing component around a portion of the insert, and bonding the reinforcing component to the insert to reinforce the insert against deformation under the application of pressure. An electromagnetic flow meter assembly is also disclosed and comprises an insert for insertion into a flow conduit, wherein at least a portion of the insert is formed of a deformable non-ferromagnetic material, wherein the insert comprises an inlet section, a measuring section, and an outlet section. The assembly further comprises at least one reinforcing component surrounding the measuring section of the insert to reinforce the insert against deformation under the application of pressure.Type: GrantFiled: February 18, 2005Date of Patent: April 26, 2011Assignee: ABB LimitedInventors: David Lincoln, Michael Armitage, David Burton

Patent number: 7866218Abstract: An electromagnetic flow meter is described having a pressure containing vessel or conduit through which the fluid to be metered is passed. The pressure containing vessel is formed of first and second sections which are made of respective materials having first and second magnetic permeabilities, such as stainless steel and carbon steel. A single magnetic field generating coil is provided adjacent the first section for generating a magnetic field across the pressure containing vessel.Type: GrantFiled: August 13, 2009Date of Patent: January 11, 2011Assignee: ABB LimitedInventors: David Lincoln, Michael Armitage

Patent number: 7665368Abstract: An electromagnetic flow meter for measuring flow rate of a fluid passing therethrough includes a conduit defining a fluid inlet, a fluid outlet and a measuring section positioned between the inlet and the outlet. The flow meter also includes a single coil for generating a magnetic field across the measuring section and electrodes for detecting induced electrical potential due to the fluid passage. The flow meter also includes means for conditioning the flow through the measuring section. The combination of the single coil and the flow conditioning means provides a flow meter with a desired level of accuracy. The single coil and the electrodes may be arranged so that the integral of a weight function, which defines the sensitivity of the flow meter to fluid velocity through different parts of the measuring section, over the first half of a measuring section closest to the coil is between 0.4 and 1.3 times the integral of the weight function over the other half of the measuring section.Type: GrantFiled: August 17, 2007Date of Patent: February 23, 2010Assignee: ABB LimitedInventors: David Lincoln, Michael Armitage

The flow meter also includes a single coil for generating a magnetic field across the measuring section and electrodes for detecting induced electrical potential due to the fluid passage. The coil may be arranged to surround a section of the measuring section over a segment angle of between 140 and 180 degrees. The electrodes may be positioned so that they are offset from being opposite each other on the centerline of the measuring section, by an offset angle of between 5 degrees and 45 degrees.Type: GrantFiled: August 17, 2007Date of Patent: November 24, 2009Assignee: ABB LimitedInventors: David Lincoln, Michael Armitage
