FIELD: possible use for checking and calibrating magnetic flow meters of liquid-metallic heat carrier of energy plants, free from electrode polarization effect.
SUBSTANCE: constant magnetic field of primary flow meter transformer is transformed to variable by rotating primary transformer around axis, coinciding with axis of primary transformer channel. By means of induction coil, positioned in channel, variable magnetic field is transformed to electrical alternating-current voltage. After integration, produced voltage by means of rectification device is transformed to constant voltage, divided by means of resistor divider and sent to input of measuring device of flow meter. Voltage at input is equivalent to signal, excited between electrodes during passage of liquid along given flow channel.
EFFECT: expanded area of possible usage.
