Details of Intelligent Vortex Flowmeter :

是一种采用压电晶体作为检测元件,输出与流量成正比的标准信号的流量仪表。 XY-LUGB intelligent vortex flowmeter is a flow meter that uses a piezoelectric crystal as a detection element and outputs a standard signal proportional to the flow rate. The meter can be used directly with the intelligent flow totalizer, or it can be used with computers and distribution systems to measure the flow parameters of different media. The instrument is based on the detection principle of fluid vortex street. The piezoelectric crystal of the vortex street is not in contact with the medium. The meter has the characteristics of simple structure, good versatility and high stability. The intelligent vortex flowmeter can be used for various gases and liquids. And steam flow detection and measurement.
Xiyuan Vortex Flowmeter
working principle:
The basic principle of the intelligent vortex flowmeter is the Carmen vortex principle, that is, "the vortex separation frequency is proportional to the flow velocity".
The diameter of the flow meter body is basically the same as the nominal diameter of the meter. As shown in Figure 1, a circular cylinder is inserted into the circulation body. The axis of the cylinder is perpendicular to the flow direction of the measured medium, and the bottom surface faces the fluid. When the measured medium flows through the column, Vortexes are alternately generated on both sides of the body, and vortices are constantly generated and separated. Two staggered rows of vortices are formed downstream of the column, that is, "vortex street". Theoretical analysis and experiments have shown that the frequency of vortex separation is directly proportional to the velocity of the column-side medium.
f = (sr * V) / d
Where:
f── the frequency of column side vortex separation (HZ);
V──column velocity (m / s);
d── width of the front surface of the cylinder (m);
Sr-Strauhal number. It is a constant that depends on the shape of the cross section of the cylinder and has nothing to do with the properties of the fluid and the velocity of the flow.
