Product Description
The E+H Proline Promass Q 300 Coriolis flow meter delivers the highest measurement accuracy for mass flow, volume flow, and density. It is the preferred choice for custody transfer applications and is optimized for liquid applications where entrained gas is present. The compact transmitter offers high operational flexibility with single-side access, remote display option, and improved connectivity.
Multi-Frequency Technology (MFT) actively compensates for gas bubbles, ensuring reliable measurement even with entrained gas. Mass flow accuracy reaches ±0.05% with PremiumCal option. Density accuracy is ±0.2 kg/m³ standard, ±0.1 kg/m³ optional. The multivariable sensor simultaneously measures flow, density, and temperature, eliminating additional process measuring points. No inlet or outlet runs are required, saving installation space.
The compact dual-compartment housing accommodates up to three I/Os with freely configurable functionality. A 4-line backlit display with touch control and WLAN access enables easy local operation. Heartbeat Technology provides integrated verification for compliance and process safety without interrupting flow.
