MIK-LUGB Vortex Type Flow Meter

Short Description:

A vortex flow meter is a type of flow meter used to measure the flow of liquids, gases, and steam in pipelines. It is based on the principle of measuring the frequency of vortices generated when a fluid flows around a bluff body. As the fluid passes the bluff body, it creates vortices that are shed alternately from either side of the body. These vortices are detected by a sensor and the frequency of the vortices is proportional to the flow velocity. Vortex flow meters are known for their high accuracy, low maintenance, and reliable performance. They are commonly used in industries such as chemical, petrochemical, food and beverage, and water treatment.

LUGB Vortex Flowmeter is on the principle of Karman street, to measure liquid, gas, and vapor even turbid liquid including micro grain and impurity. Applications: petroleum, chemical industry, paper making, metallurgy, electric force, environmental protection, food industry and etc.

Product Highlights

  • Small pressure loss, wide range, high accuracy.
  • It is hardly affected by fluid density, pressure, temperature, and viscosity when measuring volume flow under working status.
  • No moving mechanical parts, thus high reliability and low maintenance. Instrument parameters can be stable for the long term.
  • Vortex flowmeter can be used in a temperature range of -40℃ ~ +400℃.
  • It has both analog standard signals and digital pulse signal output to match with computers and other digital systems.
