FIELD: instrument-making industry, in particular, engineering of equipment for measuring flow by means of electromagnetic flow meters, their calibration and checking by imitative method. ^ SUBSTANCE: in magnetic field of primary transformer of electromagnetic flow meter induction coil is positioned. By means of magnetic field of primary transformer electronic voltage is induced. Electric voltage is integrated at output clamps of coil. Voltage produced as a result of integration is compared to voltage, noted in passport data of primary transformer. If necessary, adjustment of voltage value is performed to passport value by means of adjustable resistor. To input of measuring device of electromagnetic transformer voltage is fed through symmetric resistor voltage splitter. Voltage values are measured in flow measuring points. If necessary secondary adjustment of measuring device is performed by means of adjustable resistors. ^ EFFECT: simplified imitative method for checking electromagnetic flow meters, expanded functional capabilities of method. ^ 2 dwg |
