Vortex Flow Meter

Vortex Flowmeter Advantages:

• Integrated pressure and temperature compensation.
• 4-20mA, pulse with HART or pulse with RS485 are selectable.
• Wide temperature range up to highest temperature 350 ℃
• No moving parts, no abrasion, non-wearing parts inside, fully welded SS304 body(SS316 selectable).
• Adopt Japan OVAL technology and design
• Embedded sensor, 4 piezo-electric crystal encapsulated inside the sensor.

Vortex flow meter is one kind of speed type flow meter, It based on Karman vortex theory and adopts piezoelectric crystal to detect the burble frequency of the fluid caused by flowing through the triangular prism in the pipeline and then measure the flow of fluid.
Vortex flow meter is widely used in petrol, chemical industry, light industry and power heat supply and so on.

<p><span style="color:#000000;">When the fluid in the pipeline passes the burble generator(triangular prism),burble&nbsp;will generate due to the acceleration of partial flow rate. The burble will arise&nbsp;alternatively in two burble lines, which is called Karman vortex.</span></p>

<p><span style="color:#000000;">The releasing frequency of Karman vortex&nbsp;depends on the size of triangle&nbsp;prim and flow rate of fluid, while independent&nbsp;of the medium feature parameter,&nbsp;such as the temperature, pressure, it can be indicated by the following formulas:</span></p>
