WebFeb 20, 2024 · Flow Meter Pressure Drop, also known as Pressure loss, is one of the key indicators of flow meters. Flow Meter Pressure Drop is used to describe the pressure difference (P1-P2) before and after the flow meter input (P1) and output (P2). It is also the minimum pressure difference to ensure the normal operation of the flowmeter. WebThe Venturi effectis the reduction in fluid pressurethat results when a fluid flows through a constricted section (or choke) of a pipe. The Venturi effect is named after its discoverer, the 18th-century Italian physicistGiovanni …
