发明公开一种用于高温高压两相流探测的多探头电导探针及其制造方法。每个电导探针由外套管、内密封层、内固定架和四根金属针组成。该探针可用于高温高压条件下的矩形通道、圆管通道、棒束通道和各种异型通道内的空泡份额、界面速度、界面面积浓度等多相流参数测量。

The invention discloses a multi-probe conductance probe for high temperature and high pressure two-phase flow detection and a manufacturing method. Each conductance probe consists of an outer sleeve, an inner sealing layer, an inner fixing frame and four metal needles. The probe can be used to measure multi-phase flow parameters such as cavity fraction, interface velocity and interface area concentration in rectangular channel, circular tube channel, rod bundle channel and various shaped channels under high temperature and pressure.
