Strain type pipeline velocity sensor of vibrating reed structure and application method of strain type pipeline velocity sensor

Abstract

The invention relates to a strain type pipeline velocity sensor of vibrating reed structure and an application method of strain type pipeline velocity sensor. The strain type pipeline velocity sensor of vibrating reed structure comprises a substrate. The substrate comprises a fixing plate and fixing surfaces fixed on two sides of the fixing plate. The fixing plate is provided with a vibrating reed array. The vibrating reed array comprises fixed mounts and arrayed vibrating reeds fixed among the fixed mounts. The vibrating reeds are interconnected through connecting fibers and are connected with the fixed mounts. A closed shell is disposed on the rear of the fixing plate. Resistance strain gages are disposed between the closed shell and the rear of the fixing plate; a pipeline gauge also comprises a data processing circuit. The data processing circuit comprises convertors and data processors. The convertors are respectively connected with the pressure sensors and convert data of pressure sensors into electrical signals; the data processors are respectively connected with the convertors of the pressure sensors. The electrical signal outputted by every convertor is computed and is converted through the data processors.

Description

technical field [0001] The invention relates to a strain-type pipeline flow velocity sensor with a vibrating plate structure 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 ...
