Abstract

The invention provides a liquid level measuring pipe for rectangular narrow channel experiments and a liquid level measuring system, and relates to the technical field of mechanical devices. The liquid level measuring pipe for the rectangular narrow channel experiments comprises a pipe body and a diversion member, wherein the first end of the pipe body is a liquid inlet end, and a liquid dischargeassembly is arranged at the second end of the pipe body hermetically; the diversion member comprises a diversion part and a connecting part, the size of the diversion part gradually increases from the first end to the second end, the connecting part is fixed at the second end of the diversion part, the diversion member is fixed at the first end of the pipe body, the first end of the diversion part is close to the first end of the pipe body, the second end is opposite to the first end of the pipe body, and a fluid channel is formed between the second end of the diversion part and the inner wall of the pipe body; a first communication port and a second communication port are formed in the side wall of the pipe body, the second communication port is located at the second end of the pipe body, and the first communication port is located between the diversion member and the second communication port. The liquid level measuring pipe for the rectangular narrow channel experiments and the liquid level measuring system have the advantage that the problem of relatively complicated structure of a liquid measuring device is solved.

Description

technical field [0001] The invention relates to the technical field of mechanical devices, in particular to a rectangular narrow slit channel experimental liquid level measuring tube and a liquid level measuring system. Background technique [0002] In the process of production or scientific research, when it comes to the reaction system of gas-liquid two-phase heating (especially the heat transfer experiment of fluid in the rectangular narrow slit channel), it is often necessary to collect the liquid in the gas-liquid mixture to measure the gas-liquid in real time. The amount of liquid in the mixture. [0003] In the prior art, the liquid in the gas-liquid mixture is separated through a steam-water separator connected with the reaction system and the separated liquid is discharged to the corresponding measuring device to realize the measurement of the amount of liquid in the gas-liquid mixture . However, in the prior art, the structure of the liquid measuring device is us...
