Description

Promass Q 300 provides the highest measurement accuracy for mass flow, volume flow and density. Being the preferred choice for custody transfer applications, it has also been optimized for liquid applications where entrained gas is known to be present. The compact transmitter offers high flexibility in terms of operation and system integration: access from one side, remote display and improved connectivity options. Heartbeat Technology ensures safe processes. Measuring principle operates independently of physical fluid properties such as viscosity or density Highest measurement performance for custody transfer, density and under tough process conditions Device properties Mass / volume flow: measurement error ±0.05 % (opt.) (PremiumCal) Density: measurement error ±0.1 kg/m³ (opt.) High turndown due to low pressure loss/zero point Compact dual-compartment housing with up to 3 I/Os Backlit display with touch control and WLAN access Remote display available Benefits Secured measuring quality – unmatched accuracy of mass flow, volume flow and density Optimized performance for liquids with entrained gas – MFT (Multi-Frequency Technology) Fewer process measuring points – multivariable measurement (flow, density, temperature) Space-saving installation – no in-/outlet run needs Full access to process and diagnostic information – numerous, freely combinable I/Os and Ethernet Reduced complexity and variety – freely configurable I/O functionality Integrated verification – Heartbeat Technology
