A magnetic flow meter \u2013 also called a magmeter or electromagnetic flow meter \u2013 measures volumetric flow using Faraday's law of electromagnetic induction. A magnetic field is generated across the meter tube, and when an electrically conductive medium passes through the field, a voltage is induced that is proportional to the flow velocity. The measurement principle is independent of the medium's viscosity, temperature, and pressure, and requires no moving parts, which ensures high reliability and minimal maintenance. In hygienic versions, the magnetic flow meter is widely used in dairies, breweries, and beverage production, as well as in pharmaceutical process plants for measuring conductive process media such as water for injection (WFI) systems, solutions, and cleaning agents. An important limitation is that the measurement principle only works on electrically conductive media \u2013 typically with a conductivity above 5 \u03bcS\/cm.<\/p>","protected":false},"template":"","class_list":["post-15487","ordbog","type-ordbog","status-publish","hentry"],"acf":[],"yoast_head":"\n
