AI Technical Summary
The prior art has large errors in steam flow measurement, especially when the flow rate is less than 10, and the amplification ratio of the traditional differential pressure flowmeter is large at low flow rate, resulting in noise interference and inaccurate measurement. At the same time, the existing equipment has low detection efficiency and requires multiple shifts and alignment, which is cumbersome and inefficient.
A steam flow measurement device for heating pipes is designed, including a conveying member, a clamping member, a displacement adjustment member and a flow measurement member. By driving the motor and connecting the screw, the left and right direction position adjustment of the heating pipe and the front and rear direction displacement adjustment are achieved. The flow measuring device can move in the up and down direction and stick to the pipe surface to achieve accurate measurement of steam flow.
The device is more flexible above the fitting pipe, and is easy to detect multiple detection points, improving detection efficiency and accuracy, especially in low flow conditions, reducing errors and enhancing the stability of the system.

Abstract
Description
Technical Field
[0001] The invention belongs to the field of pipeline steam flow measurement, and in particular relates to a heating pipeline steam flow measurement device and a measurement method thereof. Background Art
[0002] When steam is transported over long distances, the size of the steam flow rate will directly affect the quality of the steam, which may cause heat loss and fail to meet user requirements. In the prior art, the flow measurement has a large rough error. The smaller the flow, the greater the measurement error. When the flow is less than 10, the error increases rapidly and the amount of steam cannot be accurately measured. Especially for differential pressure flowmeters, whether it is a standard throttling device or a balanced flowmeter, the differential pressure is proportional to the square of the flow rate. The last part of the system is a square root link. When the flow rate is very small, the magnification is very large. For example, when the differential pressure changes by 1, the displayed flow rate changes by 10. Therefore, even when the valve in the pipeline is closed and there is no flow, the small differential pressure signal caused by the pressure fluctuation of the compressible fluid such as steam or the small noise of the electronic equipment will show a considerable flow value.
[0003] When testing the steam flow of a heating pipe, workers usually hold a flow meter and stick it to the top of the steam pipe to test the steam flow of the heating pipe. However, when testing multiple test points of the heating pipe, workers are often required to perform shift measurements multiple times and need to aim at the top of the pipe multiple times, which is relatively cumbersome and has low test efficiency, and improvement is urgently needed.
