Introduction
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.
