Specifications and Product Details:

1.Working Principle:

The vortex flowmeter operates on the basis of Karman vortex street principle. If put a vertical cylinder in flow fluid,during the range of Reynolds number will alternate to form a regular vertex behind the cylinder two sides,named as Karman vortex street.The direction of vortex street is inward,up will form a clockwise rotation,down will form a counter-clockwise rotation,the frequency in single side in proportion to flowrate, in inverse proportion to the diameter of vortex producer,the relationship of them as following:

f=St×v/d

In the formula:St-Jack straw Hal number;f-frequency product by single side vortex;v-flowrate;d-diameter.

Instrument parameters K: a ratio of separation pulse amount of vortex to the volume amount:

K=N/V

In the formula:

K-instrument coefficient (pulse 1/m3)

N-pulse number (time)

V-volume amount

The relationship between the vortex separation frequency and liquid flow is as follows:

f=K×Q

In the formula:

f-frequency (time)

Q-flow (m3/h)

By testing the vortex separation frequency, the liquid flow in the pipe can be measured.
