EMCO Classical Venturi Tube as Cast with Weld end or Flange Connection KVR

{snippet mfr-emco}

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

Design standards :

• ISO 5167-4 and ASME MFC-3M
• Sizes : DN 100 - 800 according to ISO 5167
• Bore/diameter (β) : 0,3 ≤ β ≤ 0,75
• Pressure rating : PN 10 - 640, 150 - 2500 lbs, ISO PN 20 –420
• Material : Carbon steel, AISI 316, others on request
• Mounting style : Weld ends according to DIN 2559 or ANSI B16.25. Flanges acc. to DIN or ANSI B16.5 standards or Clamp connections like Grayloc
• Pressure taps : Weld ends Ø 21.3 mm, 26.9 mm, thread connection 3/8", 1/2" BSP, 1/2" NPT
• Tappings : Single pressure tappings or 4x2 tappings each arranged with an external annular ring to equalise the pressure
• Outlet cone : 7 - 15°

Technical Data

• Accuracy : 0,7 % (according to ISO 5167-4)
• Pressure loss : Depending on outlet cone between 10 - 15 % of the differential pressure measured
• Limits for Re. No. : 2 x 10 5 < ReD < 2 x 10 6
• Accessories : Shut-off valves and condensing chambers for steam flow.
