Categories:
A robust differential-pressure flow element (Venturi tube) that produces low permanent pressure loss, suited for applications requiring minimal energy loss. It handles a wide range of clean liquids and gases and is designed to international standards.
The FPD300 Venturi Tube is a classical differential pressure primary flow element, engineered for accurate and reliable flow measurement. Designed in compliance with ISO 5167, it delivers low permanent pressure loss, reducing energy consumption in pumping and compression systems. Available in sizes from DN50 to DN1200 (2–48 in.), and larger on request, it is suitable for liquids, gases, and steam, including challenging applications with some solids or wet gas.
With no moving parts, the FPD300 ensures long service life and minimal maintenance. A wide choice of materials, flange standards, and tapping options makes it adaptable to a broad range of process conditions, including high temperatures and pressures. Proven in the Oil & Gas sector, the FPD300 combines rugged design, efficiency, and precision for dependable flow metering in demanding environments.
