Abstract: A magnetic flowmeter (102) for measuring a flow of a process fluid includes a flowtube (108) arranged to receive the flow of the process fluid. Coils (222) are arranged adjacent the flowtube. First and second electrodes (224) are arranged to sense an electrical potential of the process fluid related to an applied magnetic field and a flow rate of the process fluid. The sensed electrical potential is used to calculate the flow rate of the process fluid through the flowtube (108).

A first neck flange (22) is coupled to the first end (18) of the conduit (16) and has an inside diameter (129) with a first notch (128) extending radially outwardly therefrom. A second neck flange (24,124) is coupled to the second end (20) and has an inside diameter (129) with a second notch (128) extending radially outwardly therefrom. A fluoropolymer liner (42) is disposed within and extends through the first neck flange (22), the conduit (16) and the second neck flange (24, 124). A pair of electrodes is mounted relative to the liner (42) to measure a voltage induced within a process fluid flowing through the liner (42). A first spring-energized seal ring (140) is disposed in the first notch (128) and a second spring-energized seal ring (140) disposed in the second notch (128). A method (150) of sealing a magnetic flowmeter having a fluoropolymer liner is also provided.

Abstract: A method for comparing and selecting process control equipment is disclosed. The method employs software, executed on a stand-alone computer device, or accessible through the web to retrieve data specific to a given process environment, and calculate the performance characteristics of multiple types of process control equipment capable of meeting the demands of the application. The performance characteristics of each type can be provided in graphical form, at the same time, to enable a potential user to readily discern the advantages and disadvantages of each type of process control equipment. In one embodiment, a purchase of the apparatus may then be made.
