Comparison of Vortex and Turbine Flow Meters

Abstract: The comparison information of vortex flowmeter and turbine flowmeter is provided by excellent flowmeter and flowmeter manufacturers. There are various types of instrumentation equipment used for industrial flow measurement. In the use of industrial instruments, choosing to use different instrumentation equipment due to different use occasions and environments can also be said to be a form of instrumentation today. but. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the comparison article between vortex and turbine flowmeters. There are various types of instrumentation equipment used for industrial flow measurement. In the use of industrial instruments, choosing to use different instrumentation equipment due to different use occasions and environments can also be said to be a form of instrumentation today. However, with different meters, users will inevitably make mistakes in their selection. I will introduce the comparison between vortex flowmeters and turbine flowmeters to facilitate our later choices. Although these two instrumentation devices are somewhat similar in name, they are not the same type of instrumentation in use. The vortex flowmeter is designed and manufactured according to the principle of Karman vortex. The principle of fluid oscillation is used to measure the flow. When the fluid passes through the vortex flow transmitter in the pipeline, two rows of vortices proportional to the flow rate are alternately generated up and down behind the vortex generator of the triangular column. The average velocity of the fluid is related to the characteristics of the vortex generator. Turbine flowmeters are instruments that use a multi-blade rotor (turbine) to sense the average flow rate of the fluid and derive the flow or total amount from it. Turbine flowmeters are widely used in the following measurement objects: petroleum, organic liquids, inorganic liquids, liquefied gas, natural gas, coal gas and cryogenic fluids and other aspects. It has the advantages of simple structure, few processing parts, light weight, convenient maintenance, large flow capacity (large flow through the same caliber) and adaptability to high parameters (high temperature, high pressure and low temperature). Vortex flowmeters used in the market are mainly used for flow measurement of medium fluids in industrial pipelines, such as gas, liquid, steam and other media. It is characterized by small pressure loss, large measuring range, high precision, and is almost not affected by parameters such as fluid density, pressure, temperature, viscosity, etc. when measuring the volume flow of the working condition. No moving mechanical parts, so high reliability and low maintenance. In the current market use, our users should know that the flowmeter should be used within the technical parameters of the medium working pressure and temperature range. Do not deliberately choose instruments with high pressure level and ultra-high temperature, and choose instruments according to the actual working pressure and temperature. The price of the latter is higher. The lower limit flow of the vortex flowmeter depends on the working density and kinematic viscosity of the medium, and its upper limit flow is generally not affected by the medium pressure and temperature. Therefore, to determine the flow range, it is only necessary to determine the actual available lower limit flow. After calculating the lower limit flow, check the flow range table to determine the corresponding diameter. The selection of the flowmeter should not use the flow rate to work at the lower limit value as much as possible, so the caliber of the flowmeter should be as small as possible to obtain a larger flow rate and flow range. These are some issues that need to be paid attention to when selecting and using the meter. For the use of the meter, if the user wants to use the meter more accurately to ensure the stability of its performance, he cannot relax on these details in the measurement. Understanding the measurement principle and installation technical requirements of each flowmeter provides a good theoretical basis for the correct flowmeter selection. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Comparison of Vortex and Turbine Flow Meters'
