Micro-Flow Mastery with Maximum Connectivity: Proline Promass A 300 Coriolis Flowmeter | The High-Pressure Precision Standard｜8A3C –

Product Critical Technical Advantages

• Engineering excellence in micro-flow sensitivity utilizes a unique single-tube design optimized for DN 1 to 4 (1/24″ to 1/8″) line sizes. This architecture provides the high sensitivity required to capture minute mass flow and density changes, ensuring stable and repeatable control for the most delicate dosing applications.

• Precision engineering for extreme pressure containment allows the Promass A 300 to operate safely and accurately at pressures up to 430.9 bar (6250 psi). This robustness is essential for high-pressure chemical injection and gas distribution systems where measurement integrity must be maintained under intense mechanical stress.

• Integration of operational intelligence through Heartbeat Technology provides continuous internal diagnostics and documented verification without interrupting the process. This feature is vital for micro-flow systems, as it can detect the slightest internal coating or tube wear, ensuring long-term measurement reliability and extending recalibration cycles.

• Full access to process and diagnostic data is enabled by the Proline 300 transmitter, which supports numerous, freely combinable I/Os and modern Ethernet-based protocols. With integrated WLAN access and a backlit display with touch control, operators can configure, maintain, and troubleshoot the device wirelessly or directly at the meter without opening the housing.

• Highest product quality through a self-drainable design ensures that no residual fluid remains trapped within the 1/4-inch or 1/8-inch tubes. This geometry is highly resistant to internal clogging and facilitates rapid cleaning, which is critical for maintaining high purity standards and preventing localized corrosion in sensitive process lines.

• Space-saving and lightweight installation allows the Promass A 300 to be integrated into compact modular skids and laboratory rigs where space is at a premium. Because the Coriolis principle is independent of the flow profile, it requires no straight inlet or outlet piping runs, providing ultimate flexibility in piping design.
