Working principle and installation requirements of intelligent precession vortex flowmeter

Abstract: The working principle and installation requirements of the intelligent precession vortex flowmeter are provided by the excellent flowmeter and flowmeter manufacturers and quotation manufacturers. The working principle of the intelligent precession vortex flowmeter: When the fluid flowing along the axial direction enters the inlet of the flow sensor, the blades force the fluid to perform a rotational motion, so a vortex flow is generated in the center of the vortex generator, and the vortex flow rotates in the Venturi tube to reach shrink. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the article details of the working principle and installation requirements of the intelligent precession vortex flowmeter. The working principle of the intelligent precession vortex flowmeter: When the fluid flowing along the axial direction enters the inlet of the flow sensor, the blades force the fluid to perform a rotational motion, so a vortex flow is generated in the center of the vortex generator, and the vortex flow rotates in the Venturi tube to reach The vortex flow is accelerated by sudden throttling in the contraction section. When the vortex flow enters the diffusion section, it is forced to perform precession secondary rotation due to the action of backflow. At this time, the rotation frequency of the vortex flow is proportional to the medium flow rate and is linear. The weak charge signal detected by the piezoelectric sensor is amplified, filtered, and shaped by the preamplifier to become a pulse signal whose frequency is proportional to the flow rate, and finally sent to the totalizer for counting processing. Installation requirements of intelligent precession vortex flowmeter: In the process of use, intelligent precession vortex flowmeter has relatively high requirements for the front and rear straight pipe sections. If the measured gas contains large particles or long fibrous debris, a filter needs to be installed. And the flowmeter has certain requirements for the air flow, the measured gas should be a single-phase, continuous flow through the pipe; It should be subsonic and non-pulsating, and its flow rate changes slowly with time, but for the sake of safety, it is best to install a pressure regulating valve at the front end of the flowmeter to ensure smooth and stable airflow. In order to facilitate maintenance and not affect the normal transmission of fluid due to the verification and maintenance of the flowmeter, it is required that the installation of the flowmeter should be equipped with a bypass pipeline, and the shortest straight pipe section upstream and downstream of the flowmeter should be ensured; In addition, vertical installation can also be adopted, but when non-horizontal installation is adopted, the flow direction of the fluid must be guaranteed from bottom to top. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
