摘要

Differential Pressure (DP) flow meters have been widely used since Herschel first developed the Venturi meter in the 1880s. The orifice plate meter, possibly the most popular flow meter ever, is a derivative of the Venturi meter. Weymouth introduced the orifice meter a century ago. There are also other successful DP meter designs developed from the original Herschel Venturi meter concept such as nozzle, Venturi nozzle, cone and wedge DP meters.DP meter designs are widely considered simple, sturdy and therefore reliable. They are also usually relatively inexpensive flow meters. These traits have led to DP meters being one of the most widely used flow meters in the oil and gas industry. However, in recent years with the value of hydrocarbon product increasing, with more hydrocarbon assets owned by multiple parties, and with an increase in safety requirements, the need for precise flow metering throughout the production system has become more pressing. The industry has been increasing its demand for meters that have diagnostics internal to the meter system.
