本发明公开了一种感应式液态金属电磁流量计，包括圆形流道，隔热层、励磁线圈、励磁电源、感应信号拾取线圈、信号处理模块和屏蔽层。两组励磁线圈位于电磁流量计的两端，线圈绕制方向相反，匝数相同，由励磁电源供电，励磁电源可产生高频交流电信号，两组励磁线圈在流道内产生方向相反，大小相同的磁感应强度；当液态金属不流动时，两组励磁线圈产生的感应磁场相互抵消，当液态金属流动时，会导致感应信号拾取线圈位置处的磁场发生变化，进而在感应信号拾取线圈内产生与液态金属流量成正比的交变感生电压，通过信号处理模块得到流量信号。本发明的感应式液态金属电磁流量计适用于测量液态金属的流量，如钠、锂、铅铋合金、钠钾合金等。

The invention discloses an induction type liquid metal electromagnetic flowmeter which comprises a circular flow passage, a heat insulation layer, an excitation coil, an excitation power supply, an induction signal pickup coil, a signal processing module and a shielding layer. The two groups of excitation coils are positioned at two ends of the electromagnetic flowmeter, the winding directions of the coils are opposite, the number of turns of the coils is the same, the coils are powered by an excitation power supply, the excitation power supply can generate high-frequency alternating current signals, and the two groups of excitation coils generate magnetic induction intensities with opposite directions and the same size in a flow channel; when the liquid metal does not flow, the induction magnetic fields generated by the two groups of excitation coils are mutually offset, when the liquid metal flows, the magnetic field at the position of the induction signal pickup coil can be changed, further, alternating induced voltage which is in direct proportion to the flow of the liquid metal is generated in the induction signal pickup coil, and a flow signal is obtained through the signal processing module. The induction type liquid metal electromagnetic flowmeter is suitable for measuring the flow of liquid metal, such as sodium, lithium, lead-bismuth alloy, sodium-potassium alloy and the like.
