The Proline Promass F 300 is Endress+Hauser’s top-tier Coriolis flowmeter for the most demanding applications. It measures mass flow, volume flow, density and temperature simultaneously with very high accuracy. The built-in Heartbeat Technology allows self-verification and diagnostics without stopping the process — a big reason why many plants choose it for custody transfer, dosing and critical loops.
