Flow meter

1SA1932 nozzle, also known as standard nozzle. Its design, manufacture and use are in line with the international standard ISO5167 or GB/T2624. Because its inlet part is arc-shaped and also has a certain length of cylindrical shape, its wear resistance and corrosion resistance are good, and it is often used for the measurement of liquid and gas flow at high temperature and high pressure.

Main features of nozzle flowmeter:

◆Simple structure, firmness, reliability and durability.

◆The pressure loss is smaller than the standard orifice plate, saving energy.

◆No real flow calibration is required, and the accuracy is moderate.

Main technical parameters of nozzle flowmeter:

◆Pressure method: corner contact pressure

◆Nominal pressure: ≤42MPa (≥20MPa can be welded)

◆Nominal pass through: 50~1000mm

◆Accuracy (uncertainty): ±1.0%

◆Scope of application:

Aperture diameter ratio β: 0.3≤β≤0.8

Reynolds number range ReD:

0.3<≤β≤0.44; 107≥ReD≥70000;

0.44≤β≤0.8; 107≥ReD≥20000
