Problems solved by technology

However, since the two sets of sensors are installed in different positions, the problem reflected is that the measurement results cannot reflect the flow field distribution information at the same time and at the same position, so it is difficult to reflect the complementary characteristics of ERT and ECT technologies

Abstract

A composite array transducer of ERT / ECT double mode state imaging system is prepared as having 8 - 64 electrode in ERT electrode array and the same number of electrode in ECT electrode array, setting electrode in two said arrays on internal and external wall at the same section of pipe for passing through fluid to be tested in peripheral uniform distribution type and position opposite mode by fixing bolts and sealed insulation washer, setting a radial shielding electrode between each two ECT electrodes and placing shield cover outside of shielding electrode.

Description

technical field [0001] The invention relates to an electrical imaging technology, in particular to a sensor applied to the electrical imaging technology. Background technique [0002] In the industrial production of petroleum, chemical industry, electric power, metallurgy, building materials, food, etc., there are situations where a large number of multiphase substances mix and flow. Such as oil / gas, oil / water two-phase flow, oil / gas / water multiphase flow in the petroleum industry; and gas / solid two-phase flow in various pneumatic material transportation pipelines in metallurgy and electric power industries; In the fields of chemical industry, medicine, energy, etc., the drying process, mixing process, fluidization process, diffusion process, reaction process, etc. of substances all involve the problem of multiphase flow. Therefore, it is of great significance to study the flow characteristics and changing laws of two (multi-phase) flow, and to detect its related parameters...
