High Quality Vortex Flowmeter - China

price: contact company for price

1.1 Working Principle and Application Scope

Vortex Flowmeter is one kind of main flowmeters in the international for detection and metering the liquid, gas and steam.It is widely used in Petroleum, chemical, metallurgy, heat supply industry, etc.

Setting a triangular prism vortex generator in the flowmeter, regular vortex will be generated at both the sides of triangular prism, which is called Karman swirl.As showed on the drawing 1.1, vortex are arranged regularly at the downstream of vortex generator.Suppose the vortex generation frequency is F, the average flow velocity of medium is V, d is the width of the surface of triangular prism incident flow, and D for the nominal diameter of flowmeter.Then we get the computation formula:

In the formula Sr=Strouhal number

Fitting the detection probe and related electrocircuit, then they make up the vortex flow sensor, the detection probe of LUGB-2 vortex flow sensor, adopting special structure and material, which is the improved vortex flow sensor.

1.2 Features

Detecting element does not touch with flow medium, with high reliability, and strong flexibility for medium

No moving parts, wear resistance, structure is simple and fastness

Good earthquake resistance

The allowed working temperature is wide from -40℃ to +350℃

Wide range, High accuracy

Pulse signal output or two-wire system 4-20mA current signal output
