A blood flow monitoring system employing a disposable sensor for directing a flow of blood through an electromagnetic field to generate a voltage proportional to the flow of blood through the electromagnetic field. The flow detection system employs a disposable sensor having a lumen with a constricted cross-sectional area adapted to interact with an electromagnetic field to detect blood flow and in an enhanced variation includes an electromagnetic field focusing device for enhancing the electromagnetic field to focus the electromagnetic field across the path of blood flow through the constricted section of the lumen to intensify the voltage generated by the blood flow through the intensified electromagnetic field.

Blood flow detection device

A flow tube of a ceramic material used for a magnetic flowmeter is formed to have regions of a ceramic material which has enhanced properties useful in magnetic flowmeters, such as enhanced electrical conductivity or enhanced magnetic permeability. The ceramic material having enhanced electrical conductivity is used to form sensing surfaces directly in the flow tube wall so that there is no need to have separate metal electrodes attached to or otherwise formed in the wall of the flow tube. This insures a strong, monolithic flow tube wall.
