What is the difference between a vortex gas flowmeter and a turbine flowmeter? Spiral vortex gas flowmeter: It can measure various gases for flow measurement. Turbine flowmeter: capable of rough measurement of rock orange flow rate for liquids and gases. Similarities: Uniformity can be used to measure gases. Differences: Turbine flow meters can also measure liquids. 2. Working principle of vortex flowmeter
I specialize in the sales of flow meters and have some general understanding of it.
. When fluid along the axial direction enters the sensor inlet, the spiral blades force the fluid to undergo rotational motion, resulting in the generation of vortex flow at the center of the vortex. The vortex flow rotates in the Venturi tube, reaches contraction, and undergoes secondary rotation due to the backflow effect. At this point, the rotational frequency of the vortex flow is proportional to the medium and linear. The spiral vortices I come into contact with measure gases, which have a characteristic of being greatly affected by temperature and pressure, especially pressure. Therefore, flow meters are usually equipped with temperature and pressure compensation, otherwise the measured data would be meaningless. The weak charge signal detected by the temperature and pressure sensor is simultaneously amplified, filtered, and shaped by a preamplifier before a series of operations are performed to display the data. Spiral flow is better for measuring low velocity gases, while vortex street meters are better for measuring high velocity gases. The effect of turbines is somewhat similar to theirs, but the rotating blades of turbines, especially those with small diameters, are prone to damage. The spiral blades of_600x400.jpg)
3. Differences between Spiral Vortex Flowmeters and Vortex Street Vortex Flowmeters
Although both types of flow meters utilize the principle of fluid oscillation, they use two completely different working principles.
. A flowmeter using the principle of Karman vortex: When a fluid passes through a cylindrical object, vortices are generated on both sides of the object facing away from the fluid. When one side of the vortex develops, it suppresses the vortex on the other side. When one side of the vortex develops to a certain extent, it will detach from the cylindrical object and leave with the fluid, generating a new vortex in situ. At the same time, the vortex on the other side develops due to the loss of suppression, suppressing the newly formed vortex. The above process occurs alternately on both sides of the cylindrical object, and the frequency of occurrence is related to the flow velocity of the fluid. By detecting this frequency, the flow velocity can be obtained, and the flow rate value can be obtained. Due to the alternating release of vortices arranged like objects on both sides of a road in the fluid behind, this phenomenon is also known as vortex street. A flowmeter that works based on this principle is called a vortex flowmeter or a Kalman vortex flowmeter. A flowmeter utilizing the principle of spiral vortex: a set of twisted blades are installed in the pipeline to form a vortex generator, which rotates the fluid as it passes through, forming a vortex near the centerline of the pipeline. The center of this vortex rotates around the centerline of the pipeline while expanding its rotation radius with the fluid, causing
