1、 Overview
ARSLUBThe pulse type vortex flowmeter is a new type of flowmeter developed based on the Karman vortex principle and has international advanced level. Due to its unique advantages that cannot be achieved by other flow meters, it has developed rapidly since the 1970s. According to relevant data, the proportion of smart vortex flow meters used in developed countries such as Japan, Europe, and America has increased significantly and has been widely applied in various fields. It will dominate in future flow meters and be the most ideal alternative to orifice flow meters.
ARSLUBPulse type vortex flowmeter is suitable for measuring the mass flow rate and volume flow rate of superheated steam, saturated steam, compressed air, and general gases, water, and liquids.
2、 Characteristics
The structure is simple and sturdy, with no movable parts, high reliability, and very reliable for long-term operation.
★ Easy to install and very convenient to maintain.
★ The detection sensor does not directly contact the measured medium, with stable performance and long lifespan.
The output is a pulse signal proportional to the flow rate, with no zero drift and high accuracy.
★ Wide measurement range, with a range ratio of up to
★ Less pressure loss, lower operating costs, and more energy-saving significance.
Within a certain Reynolds number range, the output signal frequency is not affected by the physical properties and composition changes of the fluid. The instrument coefficient is only related to the shape and size of the vortex generator, and there is no need to compensate when measuring the fluid volume flow rate. Generally, there is no need to recalibrate the instrument coefficient after replacing accessories.
★ Wide application range, flow rates of steam, gas, and liquid can be measured.
3、 Working principle
ARSLUBWhen a pulse type vortex flowmeter is vertically inserted into a measuring tube, the fluid alternately generates regular vortices on both sides of the column as it passes through it(As shown in the following figure)This type of vortex column is called the Karman vortex street. The release frequency of Karman vortex street is related to the flow velocity of the fluid and the width of the column, which can be expressed by the following equation: f=St·v/d
Where: f-Release frequency of Karman vortex street
St-coefficient(It is called Stroha number)
v-velocity of flow
d-The width of the columnar object
Carmen vortex street release frequencyfAnd flow ratevDirectly proportional, therefore, the instantaneous flow rate can be calculated by measuring the frequency of Karman vortex street release.
Strouhal number is an important coefficient of vortex flowmeter. On the curveSt≈0.17The release frequency of the vortex in the straight part is proportional to the flow velocity, so the detection frequencyfThe flow velocity can be obtainedv, byvCalculate the volumetric flow rate.
ARSLUBThe vortex release frequency of the pulse type vortex flowmeter is determined by the alternating action of vortices on the detection sensor(probe)The stress on it is detected through the piezoelectric elements inside.
