Proline Promass A 300
Coriolis flowmeter

Coriolis

Accurate single-tube flowmeter for lowest flow rates with a compact, easily accessible transmitter.
Suitable for applications with smallest flow quantities in all industries.

Space-saving installation – compact, lightweight sensor. Highest product quality – self-drainable measuring tube design in all line sizes. Optimum process safety – resistant to corrosive ambient conditions and internal clogging.
Nominal diameter: DN 1 to 4 (¹⁄₂₄ to ¹⁄₈"). Process pressure up to 430.9 bar (6250 psi). Medium temperature up to +205 °C (+401 °F).

Full access to process and diagnostic information – numerous, freely combinable I/Os and fieldbuses. Reduced complexity and variety – freely configurable I/O functionality. Integrated verification – Heartbeat Technology.
Compact dual-compartment housing with up to 3 I/Os. Backlit display with touch control and WLAN access. Remote display available.
