FTI just released its latest generation of electromagnetic flowmeters. Based on the principle of liquid conductance measurement, electromagnetic flowmeters allow more precise measurement in any calibration and application situation. This type of flowmeter requires that the fluids used have an electrical conductivity high enough for adequate reading.
Theory of operation:
Non-contact electromagnetic flow meters, system is called Lorentz force flowmeter (LFF). A LFF measures the integrated or bulk Lorentz force resulting from the interaction between a liquid metal in motion and an applied magnetic field. In this case the characteristic length of the magnetic field is of the same order of magnitude as the dimensions of the channel. It must be addressed that in the case where localized magnetic fields are used, it is possible to perform local velocity measurements and thus the term Lorentz force velocimeter is used.
