وصف
The vortex flowmeter lugb-50 is based on the Karman vortex principle. It is mainly used for the flow measurement of industrial pipeline medium fluid, such as gas, liquid, steam and other media. It is characterized by small pressure loss, large measuring range and high accuracy. It is almost not affected by fluid density, pressure, temperature, viscosity and other parameters when measuring volume flow under working conditions. There are no movable mechanical parts, so it has good reliability and less maintenance. The instrument parameters can be stable for a long time.
