It can not only measure the flow of the common fluids,but also measure the fluids which contains all kinds of impurity.

Annular orifice plate is offered by the American Howell in the 30’s,and it has some remodel experiments by the British NEL in the 60’s, its structure is one circular plate which is with pipeline use the same coaxial, circular plate by bracket support , the upstream and downstream of circular plate have taking pressure hole.

 

 

Main charateristics:

 

Annular orifice plate not only can measured the generally fluid flow rate .but also can be used for the measured contains all the impurities of fluid (such as dust, suspension, the precipitation etc), such as all kinds of gas, hot wind, flue-gas, natural gas, cooling recirculating water

 

♦Structure is strong, performance is  stable.

 

♦ Can measured the containing impurities of fluid

 

♦ Need the before and after straight pipe sections are shorter (before 2 D, after 0.5 D)

 

♦ Use the jacket type heat structure, and suitable for the need warming or cooling of fluid  

 

Technical parameters:

 

 

♦ Taking pressure mode: before and after side surface taking pressure.span taking-pressure

 

 ♦ Nominal pressure: ≤32MPa (≥20MPa ,it can use the welded type )

 

♦ Caliber: 50~2200mm

 

♦ Generally,  the ccuracy(Indeterminacy) is ±2.5%,  and its actual demarcated accurate can be reach ±1%

 

Range of application: open hole diameter rate β:0.5≤β≤0.72    

Reynolds number range   107 ≥ReD≥5000
