INTEGRALLY MOLDED MAGNETIC FLOWMETER

摘要

A magnetic flowmeter for measuring flow rate of a process fluid, includes a magnetic coil arranged to apply a magnetic field to the process fluid. A pair of electrodes are electronically coupled to the process fluid and arranged to sense a voltage induced in the process fluid related to the applied magnetic field and the flow rate of the process fluid. A molded flow tube of a non-conductive material is arranged to receive a flow of the process fluid. The flow tube is molded around the magnetic coil and the pair of electrodes and is configured to support the magnetic coil and the pair of electrodes. Flow meter circuitry is configured to apply a current to the magnetic coil and receive the resultant voltage sensed by the pair of electrodes.
