Abstract

The invention relates to an elastic strain type pipe flow velocity sensor and an application method thereof. The elastic strain type pipe flow velocity sensor comprises a substrate, and the substrate comprises a support plate and fixing surfaces on both sides of the support plate; the support plate is fixedly provided with a spoiler array which is composed of a plurality of spoilers perpendicularly fixed onto the fixing substrate; the spoilers and the support plate are connected in a swing mode through rubber gaskets; pressure sensors are mounted among the spoilers; the upper portion of the support plate is provided with a closed case, the edge of the closed case and the support plate are in closed connection, and an expansion cavity is formed between the closed case and the support plate. The elastic strain type pipe flow velocity sensor also comprises a data processing circuit, the data processing circuit comprises converters connected with the pressure sensors for converting data of the pressure sensors into electrical signals, and a data processor connected with the converters of the pressure sensors for computing and converting the electrical signals output by the converters.

Description

technical field [0001] The invention relates to an elastic strain type pipeline flow velocity sensor and a use method thereof, 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 so...
