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
