IMPROVED MAGNETIC CORE CONFIGURATION FOR MAGNETIC FLOWMETERS

摘要

A flowtube assembly (200) for a magnetic flowmeter (102) is provided. The flowtube assembly (200) includes a flowtube (202) configured to receive a flow of process fluid. A magnetic core (224) is mounted relative to the flowtube (202) and includes a plurality of layers (300) of a magnetically permeable material. Each layer (300) is substantially planar and is electrically insulated from others of the plurality of layers (300). A coil (216) is disposed to generate a magnetic field having field lines that are substantially orthogonal to the plane of each layer (300).
