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
