[0025] The flow meter body 1 includes a flow tube 101, which is used to allow the fluid to pass through and complete the flow measurement therein. The filter mechanism 2 is located at both ends of the flow tube 101. It directly integrates the filtering function and reduces the dependence on the external filtering system. The fixing ring 201 plays a supporting and positioning role and is fixed at both ends of the flow tube 101. The structure is provided with a first slot 202 for installing a filter plate 205. The clamping ring 203 is fixed on the outside of the fixing ring 201 and cooperates with the clamping rod 207 to achieve the fixing and removal of the filter plate 205. The filter plate 205 is located on the inner side of the fixing ring 201, directly intercepting impurities in the fluid and protecting the inside of the flow meter from pollution. The clamping piece 206 and the clamping ring 203: this structure The filter plate 205 is innovatively installed movably, allowing the filter plate 205 to be easily removed for cleaning or replacement when needed. One end of the clamping rod 207 is clamped with the clamping ring 203, and the other end is connected to the fixed sleeve 208 through a spring 209. The function of the spring 209 is to provide the necessary elastic pressure between the clamping rod 207 and the clamping ring 203, ensuring sealing while facilitating disassembly and assembly. The movable design of the filter plate 205 of this device facilitates quick disassembly and assembly, simplifies the cleaning and maintenance process, and is convenient for effectively blocking impurities in the fluid from entering the flow meter measurement area, thereby extending the service life of the equipment.
