Cone Meters differ from other differential pressure type meters, such as Orifice Meters and Venturi Meters, basically by design only. They are all required to meet API Chapter 22.2 test criteria developed and published in 2005 and still being updated today. The Cone Meter is designed to measure liquid or gas. Cone Meters are proprietary in design and have limited third party testing due to patented designs and length of use in the Industry. The Orifice Meter is the oldest meter of the three that we will discuss and has the most third party flow lab test data available. The Venturi Meter history has mostly been utilized for liquids and steam. The Venturi is also known to preform very well in harsh flows, such as sewage, waste water and pulp due to its free flowing design. In recent years Venturis are more commonly being used for LNG & CNG due to the ability to construct them from a wide variety of materials.
