[0002] With the continuous development of the industrial and chemical sectors, the application of flowmeters for liquid flow measurement is becoming increasingly widespread. Traditional flowmeters, particularly when measuring the flow of high-viscosity liquids, often face challenges due to the limitations of their measurement principles. High-viscosity liquids have poor fluidity and are easily affected by external environmental factors such as temperature changes and flow rate fluctuations during flow, resulting in reduced flow measurement accuracy. Furthermore, high-viscosity liquids can form deposits and impurities within the flowmeter, which can not only clog the flowmeter but also interfere with its normal operation, affecting the accuracy of measurement results.
