Intelligent vortex flow meter

Intelligent vortex flow meter

Overview
The kind of Intelligent vortex flow meter, which usually is mainly used for the circulation measurement of commercial pipeline medium liquid, like gas, water, steam and some other media. You will find simply no movable mechanical components, so it offers high reliability plus small maintenance. The particular instrument parameters could be stable for the long time. The particular Digital vortex circulation sensor adopts piezoelectric stress sensor along with good reliability plus can work inside the working heat range of -25 ℃ ~ +250 ℃.

Intelligent vortex flow meter will be a new kind of flowmeter along with international advanced degree, which is effectively developed based upon Carmen vortex theory. Because it has got the advantages that some other flow meters are not able to have at the particular same time, they have developed rapidly because the 1970s. According in order to relevant data, this has been popular in various areas. It is going to play the leading role within the future circulation instruments and will be the most perfect replacement for hole flowmeter.
Vortex circulation sensor is ideal for measuring mass circulation and volume circulation of superheated vapor, saturated steam, compacted air and common gas, water plus liquid。

Product software of Intelligent vortex flow meter
Intelligent vortex flow meter is mainly utilized for flow dimension of medium liquid in commercial pipe, such as gasoline, liquid, steam along with other media. Intelligent vortex flow meter is characterized simply by small pressure reduction, large measuring variety and high accuracy. It is nearly not impacted simply by fluid density, stress, temperature, viscosity along with other parameters when calculating the volumetric circulation under working problems. There are simply no movable mechanical components, therefore the Intelligen vortex flow sensor offers high reliability plus small maintenance. The particular instrument parameters may be stable with regard to a long period. The Intelligen vortex flow sensor retreats into piezoelectric stress messfühler with high dependability and can function inside the working heat selection of -20 ℃ ~ +450 ℃. They have analog regular signal and electronic pulse signal result. It really is simple to become used with electronic systems like computer systems. It is a good advanced and perfect flow instrument.

Item principle of Electronic vortex flow messfühler
In case a triangular line vortex generator will be set within the liquid, regular vortices are usually alternately produced through both sides from the vortex generator. This particular type of vortex is known as Carmen vortex road vortex. As demonstrated in the correct figure, the vortices are arranged asymmetrically in the downstream associated with the vortex electrical generator. Assuming that the particular vortex frequency will be the typical velocity of the particular measured medium will be, the width associated with the upstream surface area of the vortex generator is Deb, as well as the diameter associated with the table entire body is D, these relationship can become obtained:

Where U1 -- average speed on both edges of vortex electrical generator, M / H;
SR -- Strouhal number;
M -- ratio of ribbon and bow area on each sides of vortex generator to cross-sectional part of pipeline
The particular volume flow within the pipe QV is
