The standard orifice plate is one of the simplest and adaptable throttling devices. Its design, manufacture and use are in line with international standard IS05167 or national standard GB/T2624.
■ Can measure all kinds of gas, liquid, steam flow, adapt to a wide range.
■ Simple structure, firm, convenient installation, reliable work, stable performance.
■ No need for real flow calibration, moderate accuracy. Intelligent differential pressure ■transmitter can be used to realize temperature, pressure compensation or fieldbus communication.
Pressure taking method | Angle connection (ring chamber or separate drilling), flangepressure taking, diameter distance pressure taking. |
Nominal pressure (MPa) | ≤40 (≥20MPa with high pressure lens hole plate or full welding type.) |
Nominal diameter (mm) | DN50~1000(standard hole plate) or DN<50(internal hole plate), DN> 1000(flat hole plate) |
Precision (uncertainty) | ±0.5%~±1.5% |
The standard orifice flowmeter is widely used in petroleum, chemical, metallurgy, electric power, light industry and other sectors.
