[0003] The turbine flowmeter is a device for measuring the volume flow of fluid (liquid or gas), and its working principle is based on the momentum conversion law in fluid mechanics, that is, when fluid passes through the pipeline, if a freely rotating turbine is placed in the pipeline, the fluid will push the turbine to rotate, and the rotational speed of the turbine is proportional to the speed of the fluid.

[0004] There are still some problems in using the high-strength turbine flowmeter. When the high-strength turbine flowmeter detects liquid, when the amount of liquid in the pipeline is full, the liquid entering the flowmeter drives the turbine to rotate, and the rotational speed of the turbine can be used to calculate the speed of the fluid. However, when the internal liquid flow is small, the turbine will not rotate, and thus only a turbine flowmeter with smaller pipe diameter can be used to solve the problem, thereby resulting in low applicability of the high-strength turbine flowmeter. Therefore, a high-strength turbine flowmeter needs to be proposed. UTILITY MODEL CONTENTS
