1. Principle of Differential Pressure Flow Measurement When a fluid completely fills a pipeline and flows through a primary element (such as an orifice plate or nozzle), a local constriction is created. This results in an increase in velocity and a decrease in static pressure. Consequently, a differential pressure (DP) forms before and after the
