1. Working principle and advantages of intelligent vortex flowmeter
Vortex flowmeter application HLUG series intelligent vortex flowmeter, mainly used for flow measurement of industrial pipeline medium fluids, such as gas, liquid, steam and other media. Its characteristics are small pressure loss, large range, high accuracy, and it is almost unaffected by parameters such as fluid density, pressure, temperature, viscosity, etc. when measuring the volumetric flow rate of Tongdouxun under working conditions. No movable mechanical parts, therefore high reliability and low maintenance. The instrument parameters can be stable for a long time. This instrument uses piezoelectric stress sensors with high reliability and can operate within a temperature range of -20 ℃ to+250 ℃. It has both analog standard signals and digital pulse signal outputs, making it easy to use in conjunction with digital systems such as computers. It is a relatively advanced and ideal flow meter. The principle is to set up a triangular cylindrical vortex generator in the fluid, which alternately generates regular vortices from both sides of the vortex generator. This type of vortex is called a Karman vortex, as shown in the figure on the right. The vortex columns are asymmetrically arranged downstream of the vortex generator.
2. Introduction to Intelligent Vortex Flow Meter
The intelligent vortex flow meter model is SYLU, mainly used for flow measurement of industrial pipeline medium fluids, such as gas, liquid, vapor and other media.
. No movable mechanical parts, therefore high reliability and low maintenance. The instrument parameters can be stable for a long time. The vortex flowmeter adopts a piezoelectric stress sensor wi
(1), where U1 represents the average flow velocity on both sides of the vortex generator, m/s； Sr Strouhal number; The ratio of the bow shaped area on both sides of the m - vortex generator to the cross-sectional area of the pipeline is qv, which is qv=π D2U/4=π D2mdf/4Sr (2) K=f/qv=[π D2md/4Sr] -1 (3). In equation K - the instrument coefficient of the flowmeter is the number of pulses/m3 (P/m3). K is not only related to the geometric dimensions of the vortex generator and pipeline, bu
