LUGB series Vortex-shedding Flow Meter

 

 

 

 

 

Scope
Gas: air, oxygen, carbon dioxide, nitrogen, natural gas, biogas, etc;
Liquid: water, oil, etc;

 

Steam: saturated steam and superheated steam.

 

 

 

1.1 Work Principle
     Setting a triangle vortex shedder in the fluid, and some regular vortexes generate at both sides of the vortex shedder alternately. This kind of vortex is called Karman vortex. The vortexes asymmetrically arrange in the downstream of the vortex shedder.

 

 

 

1.2 Features
a. The detecting element does not touch the fluid, with the high reliability and high adaptability for the medium.
b. No moving parts, with the characteristic of wear-resistant, Solid and simple structure.
c. Wide measuring range, High accuracy
d. Low pressure loss
e. Pulse signal output.
f. Low metering cost.
