LUGB Vortex flowmeterDetailed product description：

I. Overview
The LUGB vortex flowmeter utilizes the "Karman vortex street" measurement principle to measure the volumetric flow rate of the medium in a closed pipeline. It has many advantages that cannot be achieved by other flowmeters and has developed rapidly since the 1970s. Compared to turbine flow meters, it has no movable mechanical components, resulting in smaller maintenance requirements, stable instrument constants, and ease of ensuring accuracy in working environments. Compared with orifice plates, it has a larger measurement range, smaller pressure loss, and higher accuracy. Vortex flowmeter belongs to fluid vibration flowmeter, which can be used to measure saturated steam, superheated steam, various gases (such as coal gas, natural gas, compressed air, oxygen, nitrogen, argon, hydrogen, carbon dioxide, etc.), water and low viscosity, low-temperature liquids (such as salt water, liquid nitrogen). Gas liquid universal, no need for real liquid calibration; Can accurately measure the flow rate of steam, gas, and liquid in closed pipelines. There are various types available for selection, including anti vibration, anti-corrosion, high temperature, explosion-proof, etc. DN200 and above are insertable; Suitable for industrial processes such as metallurgy, chemical industry, petroleum, gas, urban water supply and drainage, food, textile, mining, energy management, and environmental engineering industries.
