METHOD FOR SIMULATION TECHNIQUE OF ELECTROMAGNET FLOW METERS Russian patent published in 2016 - IPC G01F25/00 

FIELD: electronics.

SUBSTANCE: invention relates to simulation method for simulating electromagnet flow meters with use of induction coil, placed into channel of flow meter, and for determining conversion coefficient K_p. Method enables simulating electromagnetic flow meter in measurement of flow rate of liquid metals, and at high magnetic Reynolds numbers Re_m. Simulation method for effect of magnetic Reynolds number upon signal of flow meter consists in following. Values are set for volumetric flow rate of liquid metal Q, for which K_p determination is necessary. For these values of volumetric flow rate, magnetic Reynolds numbers are calculated, further, conformity of value λ to specified values Q and Re_m is either calculated, or is taken based on experimental materials. Placing Induction coil in accordance with calculated values λ, transformation coefficients are determined K_p. Then relationship between volumetric flow rate and coefficient K_p in whole range of measured flow rates is plotted.

EFFECT: technical result is increase of accuracy of simulation technique of electromagnet flow meters in conditions corresponding to high magnetic Reynolds numbers.
