Abstract
A magnetic flowmeter comprises a pipe section, an insulating liner, a flangeless retention collar, a liner protector, a coil and an electromotive force sensor. The insulating liner lines the pipe section to form a process flow channel. The flangeless retention collar is located on an end of the pipe section for forming an end-to-end fluid connection to the process flow channel, and the liner protector is formed on the retention collar to provide an end seal for the insulating liner. The coil produces a magnetic field within the process flow channel, and the electromotive force sensor senses an electromotive force generated in fluid flow through the process flow channel.
