orifice meter

Orifice plate flow meter simple structure, easy installation; reliable performance; wide application; high accuracy;

1. Orifice plate flow meter

    Orifice plate liquid / air / gas measuring instrument / tool  is a kind of standard throttling device with the most models. They are widely used in the measurement of many kinds of fluid, especially gaseous fluid. The structure of orifice plate varies with the difference of nominal pressure, nominal diameter and pressure tapping mode. According to the main pressure tapping mode, standard orifice plate can be classified as corner taps(include annular chamber bore taps and single bore taps) orifice plate, flange taps orifice plate, radius taps(D and D/2 taps) orifice plate.

 

 

Pressure tapping mode	corner taps		flange taps	radius taps(D and D/2 taps)
	annular chamber bore taps	single bore taps
Operating conditions	d≥12.5mm, DN:50~1600mm, β=0.20~0.75		d≥12.5mm, DN:50~1000mm, β=0.20~0.75	d≥12.5mm, DN:50~1000mm, β=0.20~0.75
Accuracy	±1.5%~±0.5%

2. Annular orifice plate    It is not only able to measure the flow of general fluid, but also fluid with various impurities like dust, suspended substance, sediment, such as hot coal gas, flue gas, natural gas, circulation cooling water, etc..Specifications: 

Caliber(mm)	50~2600(larger size available for special order)
Pressure(MPa)	≤42
ReD range	General type: 4×103-1×107; High viscosity type:1×103-1×105(calibration)
Accuracy	Real flow calibration: ±1%, ±1.5%; Sample calibration: ±2.5%
Connecting mode	Flange connection, Welding
