Abstract
Disclosed is an electrical capacitance volume tomography applied to flow monitoring in a Venturi tube of a cryogenic fluid (such as liquid nitrogen (˜78K) and liquid oxygen (˜90K)). The device includes a conductor rod, a metal shell, a Venturi tube, an electrode plate sleeve, an electrode plate and annular connecting shells. According to the device, an electrode plate and electrode plate sleeves which are attached to the surface of a Venturi tube are arranged according to the variable-diameter characteristic of the Venturi tube, meanwhile, a corresponding wire connecting structure is designed, and a shielding shell is designed according to the characteristic that electrical capacitance volume tomography needs shielding. The device has the advantages of being simple and stable in structure, easy to disassemble and assemble, capable of being disassembled and assembled many times and capable of being rapidly connected with other pipelines.
