Integrated Standard Orifice Plate

Its structure is simple and strong. It can be installed conveniently.

Standard Orifice Plate is one of the most adaptable products of the throttle devices. Its structure is simple. It can be installed conveniently. Its design, manufacture and use are all in compliance with the stipulations of ISO 5167 or GB/T.

 

Main Characteristics:

  ♦ Its structure is simple and strong. It can be installed conveniently. 

♦ It is widely used, and can measure the flow of all kinds of gases, steams and liquids.

♦ There is no need to calibrate the real flow. Its accuracy is moderate.

♦ Its accessories are complete, which can be designed and calculated for the user.

♦It can be equipped with the intelligent differential- pressure transmitter to realize the temperature & pressure compensation or the communication mode of the scene bus.

 

Main Technical Parameters:

 

♦ Mode of Taking Pressure:

Fillet Weld (Annular chamber or separated drill hole) pressure-taking,

Flange pressure-taking , 

D-D/2 pressure-taking.

 

♦ Nominal Pressure:  ≤32MPa 

Note: when it is ≥20MPa , the high pressure lens orifice plate or the welded type can be selected.

 

♦ Norminal Caliber: 

50~1000mm (standard orifice plate);

or 

or >1000mm (planus orifice-plate)

 

♦ Accuracy(Indeterminacy): ±1.0%

 

♦ Range of Application:

 Hole-opening diameter d(mm): d ≥12.5 (standard orifice plate)

 Hole-opening diameter rate β:  0.1 ≤ β ≤ 0.75

 Reynolds number range ReD:  0.1 ≤β≤ 0.75,

                                              107 ≥ReD≥5000, and ReD≥170 β2D;

                                              D is expressed by mm.
