SUP-LUGB Vortex flowmeter work on the principle of generated vortex and relation between vortex and flow by theory of Karman and Strouhal, which specialize in measurement of steam, gas and liquid of lower viscosity.
Fully Isolated Structure CircuitAnti-vibration high-quality filter processing.
Simple StructureVortex flowmeter sensor structure is simple, there is no movable parts in the tube, there is no throttle parts that can impede the flow of fluid, is one of the flowmeter products in the operation of low energy consumption flow meter.
Wide Range Of ApplicationsElectromagnetic flowmeter can measure dirty media, but to be in the measurement process also need to pay attention to avoid contact with corrosive properties of the liquid; and vortex flowmeter can not only measure sewage, but also can measure with corros
Extremely Wide Range UnitVortex flowmeter output is only proportional to the average flow rate of the measured medium, and has nothing to do with the flow state under the symmetrical distribution. Therefore, the vortex flowmeter range unit is extremely wide, its measurement range degree up to 100:1, sometimes even up to 1000:1 can run the flow range.

A fluid flowing with a certain velocity and passing a fixed obstruction generates vortices. The generation of vortices is known as Karman’s Vortices.The frequency of vortex shedding is a direct linear function of fluid velocity and frequency depends upon the shape and face width of bluff body. Since the width of obstruction and the inner diameter of the pipe will be more or less constant, the frequency is given by the expression: f=(St*V)/c*D
The magnetic inductive flowmeter industry, these are successful cases with comparable and reference value.
In order to reduce measurement errors, whether it is a wafer-type vortex flowmeter or other types of vortex flowmeters, the pressure measurement point should be selected after the table.
