Classic Venturi Tube can be also called Classical Venturi Tube, which design, production and use are in compliance with the stipulations of ISO 516 or GB/T 2624. It’s widely used to measure the flow of liquids and gases.

Main Characteristics:

♥Its structure is Simple and firm; its performance is stead.

♥ The loss of its pressure is small.

♥ The size of its structure is large; the size of installation is long.

♥ Generally it needs no real flow to calibrate; while it needs calibrating the real flow.

Technique Parameters:

♦ Mode of Taking Pressure:

It takes the pressure with the diameter pitch for the upstream part; while it takes the pressure of the throat part for the downstream part.

♦ Nominal Pressure: ≤6.3MPa

♦ DN (Nominal Diameter): 50~2200mm

♦ Accuracy(Indeterminacy): ±1.5%

♦ Range of application:

Diameter rate of the opening hole β: 0.4≤β≤0.7

Range of the Reynolds number ReD : 2 *10⁶ ≥ReD≥ 2* 10⁵

Efflux Coefficient C: C=0.985
