The TidalFlux electromagnetic flowmeter includes the models IFM 4110 PF and IFM 4210 PF. It is used to measure the volumetric flowrate of electrically conductive liquids in partially filled pipelines. It is combined with a capacitive flow-level measuring system built into the wall of the measuring tube, providing accurate flow measurements in partially filled pipelines, with levels between 10% and 100% of the pipe cross-section.
