1. Working principle of intelligent vortex flowmeter

Working principle of intelligent vortex flowmeter: Intelligent vortex flowmeter is a flow measurement instrument based on fluid dynamics principles, and its working principle mainly depends on the vortex flow and precession phenomenon generated by the fluid in a specific structure.

First, the structural characteristics of the flow sensor. The flow profile of the intelligent vortex flowmeter flow sensor is similar to the profile of the Wenqiu Li tube Qingzi rent, which helps the fluid to form a stable flow state inside the sensor.

. On the entrance side, there is a set of spiral guide vanes. The function of these blades is to force the fluid entering the flow sensor to generate intense vortex flow.

Second, the generation and precession phenomenon of vortex flow: When the fluid passes through the spiral guide vanes, the guidance of the vanes causes the fluid to produce a turbulent rotational motion, forming a vortex flow.

. This vortex continues to exist inside the sensor and advances forward with the flow of fluid. Precession phenomenon: When the fluid enters the diffusion section of the sensor, the vortex flow is subjected to backflow and begins to undergo a second rotation. This secondary rotation forms a gyroscopic vortex precession phenomenon. This precession frequency is directly proportional to the flow rate, that is, the larger the flow rate, the higher the precession frequency. This feature enables the intelligent vortex flowmeter to accurately measure flow rate.

III. Signal Detection and Processing: The sensor is equipped with a detection element inside, which is used to measure the frequency of the secondary rotation and p

recession of the fluid.

. This frequency signal is the key data for flow meter measurement. Signal processing: The detected frequency signal is first amplified by a preamplifier, and then converted into a pulse signal proportional to the flow rate through filtering and shaping processing. This pulse signal is then sent to the microprocessor for integration processing along with temperature, pressure, and other detection signals. 4. Display and Output of Measurement Results After being processed by the microprocessor, the measurement results (including instantaneous flow rate, cumulative flow rate, temperature, and pressure data) are sent to the LCD screen for display. Users can visually view measurement results through the display screen and record or transmit them as needed.

Fifth, Schematic Diagram of Working Principle From the schematic diagram, it can be seen that the structure of the intelligent vortex flowmeter is compact and the design is clever.

. When the fluid passes through the sensor, it is guided by the spiral guide vanes to form a vortex flow, and precession occurs in the diffusion section. The detection element captures this precession frequency and converts it into an electrical signal for processing and display. 6、 The working principle of the intelligent vortex flowmeter is based on the vortex flow and its precession phenomenon generated by the fluid in a specific structure. By measuring the precession frequency of vortex flow, the flow rate of the fluid can be accurately calculated. This flowmeter has the advantages of accurate measurement, good stability, and wide applicability, and has been widely used in industrial production.
