Vortex Flow Meter

Vortex flow meters are based on Karman vortex principle.It’s utilized across various applications including liquid, gas, saturated steam, and superheated steam. It’s widely employed in industries such as oil and gas, chemical processing, power generation, and water treatment, due to its capability to accurately measure flow rates in diverse fluid conditions.
1>Measure accuracy: ±1%R，±1.5%R
2>Pipe size: DN 15 mm ~300 mm
3>Working temperature: -40°C~+350°C
4>Flow output signal: 4-20mA,/pulse
5>Supply voltage: 24VDC/12VDC，3.6VDC
6>Sensor connection: Flange
7>Protection class: IP67

YFV(1)

Working Principle:

When a bluff vortex generator (bluff body) is set in the fluid, two regular vortex generators are alternately generated from both sides of the vortex generator. Vortex, this kind of vortex is called Karman vortex street.

The rows of vortices are arranged asymmetrically downstream of the vortex generator. Suppose the frequency of vortex occurrence is f, the average velocity of the incoming flow of the measured medium is V, the width of the vortex generating body is d, and the diameter of the surface body is D. According to the principle of Karman vortex street, there is the following relationship:

f=StV/d

In the formula: f- the frequency of the Karman vortex generated on one side of the generator
St-Strohal number (dimensionless number)
V-fluid Average velocity
d – the width of the vortex generator

It can be seen that the instantaneous flow can be calculated by measuring the separation frequency of Carmen Vortex. Among them, the Strohal number (St) is a dimensionless unknown.

YFV series Vortex flow meters are designed for measuring the volume/mass flow of liquids gases and steam based on Karman vortex principle.
Adopting advanced differential algorithm along with measurement of isolation, shielding and wave filtering, YFV series vortex flow meters have the advantages of immunity on vibration and noise. Meanwhile, the liabilities of YFV series vortex flow meters are well guaranteed by unique sensor packaging technology
