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.
Low pressure lossWhen measuring fluid flow, vortex flow meters are designed so that less pressure loss occurs as the fluid passes through, which helps to reduce the energy consumption and operating costs of the system.
Large measuring rangeThe range ratio of vortex flowmeter can generally reach 1:10, can cover a wide range of flow measurement range, applicable to a variety of different flow demand scenarios.
High precisionVortex flowmeter in the measurement of work volume flow rate is almost independent of the fluid density, pressure, temperature, viscosity and other parameters, so it has a high measurement accuracy. Its repeatability is generally 0.5%, high accuracy.
High reliabilityVortex flowmeter has no moving mechanical parts, simple and solid structure, long-term operation is very reliable. At the same time, its instrument parameters can be stabilized for a long time, and the maintenance is small.
Wide range of applicationsVortex flowmeters can be used to measure the flow of gases, liquids, steam and other media, with a wide range of applicability.
Easy to install and maintainVortex flow meters are relatively simple to install and maintain, reducing the user's cost of ownership.

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
