The SKLU series vortex street flowmeter mainly uses in the industry pipeline medium fluid the flow measurement, like gas, liquid, vapor and so on many kinds of medium. Its characteristic is the pressure loss is small, the measuring range scope is big, the precision is high, when survey operating mode rate of volume flow nearly not parameter and so on fluid density, pressure, temperature, viscosity influences. Not movable machine parts, therefore the reliability is high, maintains the quantity to be small. The measuring appliance parameter can the long-term stability. The vortex street flowmeter uses the piezoelectricity stress type sensor, the reliability is high, may in - 20℃~+250℃ the operating temperature scope works. Has the mock standard signal, also has the digital pulse signal output, easy and number system necessary uses and so on computer, is one kind quite advanced, the ideal flow instrument.
Vortex street flowmeter principle
Establishes the triangle columnar order whirlpool in the fluid to have the body, has the body both sides from the whirlpool to produce alternately has the rule whirlpool, this kind of whirlpool is called the Carmen whirlpool, if the figure to the right shows, turns on lathe the vortex street to have the body downstream in the whirlpool to arrange asymmetrically.
Supposes the whirlpool the occurrence frequency is f, was measured that the medium mean velocity of stream is, the whirlpool has the body to welcome the flow surface width is d, shows the body latus rectum is D, then obtains the following relationship:
f=SrU1/d=SrU/md (1)
In the formula U1--The whirlpool has the body both sides mean velocity of stream, m/s;
Sr--Strouhal number;
m--Of the whirlpool has ratio of the body both sides arch area and the pipeline cross-section area
In the pipeline rate of volume flow qv is
qv=πD2U/4=πD2mdf/4Sr (2)
K=f/qv= [ |
