Description

technical field [0001] The invention relates to a pipeline flow velocity sensor and a usage method, belonging to the field of pipeline flow velocity sensors. Background technique [0002] As a device for measuring the velocity of water flow, the flow meter can be divided into several categories according to the field, such as mechanical type, optical type, and acoustic wave type, among which: [0003] The optical type and the acoustic wave type have high data acquisition accuracy, timely flow rate feedback, and no attenuation on the pipeline flow rate. They are widely used in some high-precision fields, such as: pharmaceuticals, precision chemicals, fluid model building, pipelines and pumps, etc. Precision fluid conveying equipment testing, etc.; optical type and acoustic type are mainly manufactured through media such as sound waves and electromagnetic waves, using the concept of different attenuation effects and different propagation speeds on sound waves and electromagnet...
