Rev.4 ‐ 2013 

Orifice plates, carriers and orifice flanges

      Orifice Plate types          • Square Edge 

o For general applications in clean fluids. The most widely used design. Suitable for pipes up to 1000 mm diameter.  

• Quarter Circle o Suitable for measurement 

of low Reynolds number flows in pipelines of diameter less than 750mm 

• Conical Entrance o Suitable for measurement 

of very low Reynolds number flows. Easier to manufacture than Quarter circle type. 

• Segmental o Suitable for measurement 

of dirty fluids and 2 phase flow. Allows passage of extraneous matter. Suitable for pipes up to 350mm 

• Eccentric o Suitable for measurement 

of dirty fluids and 2 phase flow. Suitable for pipes up to 350mm 

• Restriction o Not for flow measurement 

but to reduce the pressure in the pipeline.   

      Benefits • Exotic materials for demanding 

services ‐ Duplex, 6MO (M650) • Minimal maintenance required • Available in sizes from 1/2” and up • Manufactured to suit customers 

application • Used to measure a wide range and 

mediums • Design according to a well know 

standards • Standard tapping's or welded on 

piping valves • High pressure solutions 

 

Orifice plates are the most popular device for measurement and control of fluid flow. The shape and manufacturing tolerance of plates used in measurement applications are defined in international standardization publications of ISO, AGA, ASME and others. Based on data from the process and formulas from these publications we get the relationship and values of flow, differential pressure and plate bore. Autek Orifice plates are manufactured to meet strict industry standards and safety guidelines and are designed to meet the end users expectations.
