A system and method for measuring the velocity of a high-temperature melt

Abstract

The invention provides a system and method for measuring the velocity of a high temperature melt. The system comprises a power supply, a switch, an adjustable resistor, a signal load, a detection metal wire, a high frequency data acquisition system, a PC terminal and a signal transmission cable. The number of signal branches is determined by a number of spatial location points with the need of the measurement of the velocity of the high temperature molt, and the resistance of the adjustable resistor is adjusted according to the branch number so as to ensure that the voltage of a load resistor in each branch is in a scope of recognition and acquisition. Through synchronizing the high frequency data acquisition system, a voltage signal of the signal load is collected and processed and is transmitted to the PC terminal to be displayed and recorded. Based on the high temperature melt, the detection metal wire can be melted, and thus the voltage signal of the signal load changes suddenly. According to a mutation time interval and a detection metal wire space distance, the velocity of a high temperature melt is measured. According to the system and the method, the interference and influence of the high temperature melt flow are small in a measurement process, and the velocity of the high temperature melt can be measured effectively.

Description

Technical field [0001] The invention relates to the technical field of fluid velocity measurement, in particular to a high-temperature melt velocity measurement system and method. Background technique [0002] The high temperature melt is extremely high temperature and has great corrosive characteristics. The traditional speed measuring instrument is difficult to be applied in high temperature environment due to the limitation of its measuring principle. Non-contact measurement, such as the use of image processing technology or radiographic measurement technology, due to the need to take pictures of the high-temperature melt, there must be no obstacles or penetration between the lens or the radioactive source and the high-temperature melt. The window may cause the window to burst or the sealing effect is not good, so it is difficult to open the window in a high-temperature environment or a complex structure. Use image processing technology to measure the speed of high-temperature...
