◆ Orifice plate with ring ◆
● Model : F200 series
● Description :
Orifice ring assemblies are used for flow measurement of smaller or medium sized pipes at lower pressure. Each assembly consists of one orifice plate and two orifice rings at lower pressure. Each assembly two orifice rings. Differential pressure is taken out in a corner tap system. Orifice block, which are of a unit-construction type and provide higher pressure ratings than the orifice ring assemblies, also are available.
● Orifice bore type :
- Concentric square edged orifice
- Quadrant edged orifice
- Minimum quadrant edged orifice diameter 4.5 mm
- Minimum quadrant edged radius 0.5 mm
● Flow calculation standards :
- ISO 5167-1 and 2 2003
- AGA-3
- ASME MFC-3M and 14M
- JIS Z 8762
- BS 1042
● Flange ratings :
- JIS 5, 10, 16, and 20K
- ANSI (or JPI) 150 and 300 Lb
(Note: ANSI and JPI ring dimensions are identical)
● Pressure taps : Corner taps
● Plate thicknesses : 3, 6, 9 and 12 mm
● Tab handle : Welded to orifice plate
● Pressure tab nipples
