Orifice Plate MES

Orifice Plate with Single Pressure Tapping Series in all Welded Construction MES

EMCO orifice plates are used as primary elements in flow measurement of steam, liquid, and gas according to the differential pressure principle.

• Tap location : Tap location for steam flow: 180°. At least 45° apart for liquid and gas. To be stated with order
• Marking : The orifice plate is marked with "+" and "-" and flow direction.
• Accessories : single and double shut-off valves and condensing chambers for steam flow measurement
• Technical Data
• Accuracy : +/- 0,5 % for β < 0,6 and equal to β for β values above 0,6
• Pressure loss : Depending on β, for β equal to 0,6 : ca. 60 % of the differential pressure measured
• Limits for Reynolds No : Re > 1260 x β2 D according to ISO 5167, 2000 < Re < 108 according to ASME MFC-3M?
