• ISO 5167-3
• Sizes : DN 50 - 500
• Pressure rating : PN 10 - 400, 150 - 2500 lbs
• β (d/D) : 0.3 < β < 0.8
• Material : Carbon steel P250GH, AISI 316, 16Mo3, 13CrMo4-5, 10CrMo9-10, WB 36, X20CrMoV121, P91, P92, other materials on request
• Mounting style : Weld ends according to DIN 2559 or ANSI B16.25
• Pressure taps : Ø 21.3 mm, 24 mm, 26.9mm, 3/8", 1/2" BSP, 1/2" NPT
• Tap lengths : 150 mm, others on request.
• Tap location : At least 45° apart. For steam flow in a horizontal pipe : 180° To be stated with order.
• Tappings : Single pressure tappings
• Tap lengths : 150 mm, others on request

Technical Data

• Accuracy : 0,8 % for β < 0,6, (2β - 0,4) % for β > 0,6 (according to ISO 5167-3)
• Pressure loss : Depending on β, for β equal to 0,6 : ca. 60 % of the differential pressure measured
• Limits for Re. No. : 2 x 10 4 < ReD < 1 x 10 7 according to ISO 5167-3
• Accessories
• Shut-off valves and condensing chambers for steam flow measurement
