Venturi Meters
Benefits Options • High Accuracy, precision machined
venturi • Minimal maintenance required • Available in sizes from 2” to 60” • Manufactured to suit customers
application • Used to measure a wide range and
mediums • Short, long and truncated forms
available • No moving parts = no maintenance • Design according to a well know
standards
• Exotic materials for demanding services – Duplex, 6MO (M650)
• High pressure solutions • Wide temperature ranges • Meter Runs and instrumentation • Standard tapping’s or welded on
piping valves • Specials for drilling, mud and subsea • Calibration with hot water or gas
Autek Venturi Meters are manufactured to meet strict industry standards and safety guidelines and are designed to meet the end users expectations. Venturi meters are used on applications where a low permanent pressure loss is desired. This type of ‘Differential Pressure Meter’ can be used on a wide variety of flow mediums and include slurry, heavy oil, sludge, liquid, vapour, gas and high pressure steam. Autek Venturi meters are produced using 3 main manufacturing methods, selected to best suit the material and size of the meter. These are detailed in ISO 5167-4:2003 and permit the use of specific Beta ranges.

Venturi Meters
Body Configuration • Flange x Flange • Flange x Weld required • Weld x Weld
Flanges available in the following
standards; • ANSI 16.5, DIN • Techlok • SPO • Graylok • API 6A • FF, RF, RTJ, CF (L‐005)
Long form / Short form / Truncated
• Long form – Venturi meters with 7º exit angle. Longer lay length with lower non‐recoverable pressure loss
• Short form – Venturi meters with 15º exit angle. Shorter lay length with non‐recoverable pressure loss slightly higher than Long form.
• Truncated form – Allow a 33% reduction in the outlet cone length. Non‐recoverable pressure loss affected.
Pressure Tap Options
• NPT taps • Flanged taps • Piezo Annular rings • Valved taps
Design Codes • ASME B31.8 Gas Transmission and
Distribution • NACE MR‐01‐75 • ASME B31.1 Power piping • ASME B31.3 Liquid Petroleum
Transportation • PED 97/23/EC ‐Pressure Equipment
Directive
Measurement Standards • ISO 5167‐4:2003 • ASME MFC‐3M
Painting
• NORSOK M501 • TR 0042 • Other on request
Autek Venturi meters meet all requirements according ISO5167‐4:2003, NORSOK and Statoil TR. Autek AS is certified according to ISO 9001:2008 and has procedures to meet customer’s requirement to offshore deliveries.
