Introduction

ME2400 Vortex Flowmeter works on the Karman vortex street principle that swirls generated by a bluff body in the pipe. The number of swirls are proportional to the volumetric flow in the pipe. Vortex flowmeter widely used for gases, steam and liquid applications. It is ideal for measuring saturated and superheated steam in large facilities to improve steam production efficiency.

Principle

When the fluid in the pipeline passes the bluff body (triangular prism), vortices will be generated due to the acceleration of partial flow rate. The vortices will arise alternatively in two lines, which is called Karman vortex. The releasing frequency of Karman vortex depends on the size of triangle prim and flow rate of fluid, while independent of the medium feature parameter, such as the temperature, pressure, it can be indicated by the following

formulas:

F=sR*v (1-1.27*d/D) | Q=3600*F/K | M=Q*P
