SYNERGIZE software, electronics, and primary element

摘要

A new generation of dP measurement instrumentation eliminates traditional limitations. In the year 1724, Bernoulli's streamlined equation outlined the principles that form the basis of today's differential pressure (dP) flow measurement. This equation defines the relationship between kinetic and potential energy in a flow stream. It allows the calculation of volumetric flow rate based on the measurement of dP across a restriction. dP-based measurement has a history that reaches back to ancient times, as well as the largest installed base of any process flow technology. dP flow measurement continues to be the most frequently specified flow technology, not because of its tradition in flow measurement but because of the value it offers. While new flow measurement technologies have emerged that have strength in certain applications, the dP flowmeter remains a favorite for process flow applications because of its application flexibility, excellent repeatability, proven reliability, direct process mounting, ease of calibration and troubleshooting, worldwide industry standardization, low installation and operating costs, and meter inter-changeability, among other things. Recent developments in dP flow measurement bring the primary element (differential producers such as the venturi, orifice, and nozzle) together with the secondary element (dP measurement instrument). The synergy of software, electronics, and primary element allows the end user to save on installation costs and improve reliability. Enhanced dP flowmeters allow compensation for the dynamic variation of process conditions and primary element flow coefficients.
