Standard Orifice Plate

This 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(annular chamber bore taps&single bore taps), lange taps, radius taps(D and D/2 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%
