FIELD: physics.
SUBSTANCE: flow rate transducer comprises medium flow measurement tube 1, measuring electrode device 3 to register electric voltage generated in flowing medium, and system 2 to induce magnetic field arranged outside on measuring tube. Holder 23, 24 serves for fixation of, at least, one excitation coil 21, 22 outside on measuring tube, and is made up of coil core conducting magnetic field made integral with measuring tube so that the tube and the holder are jointed together without joint seam. Pole shoe 27 that focuses magnetic field is arranged on interface between coil holder and measuring tube and made by, for example, local bulge of measuring tube wall. Magnetic field system 2 may comprise, at least, one closed element 25 conducting magnetic field around measuring tube and jointed with appropriate coil holder.
EFFECT: higher accuracy of measurements, reduced number of assembly parts.
