The compact Promass A is ideal for continuous process control in very demanding applications. Its unique self-drainable single-tube system enables accurate measurement of liquids and gases at lowest flow rates and high pressure. With its innovative remote transmitter Promass A 500 maximizes installation flexibility and operational safety in demanding environments. Heartbeat Technology enables measurement reliability and compliant verification.
Measuring principle operates independently of physical fluid properties such as viscosity or density. Suitable for applications with smallest flow quantities in all industries. Accurate single-tube flowmeter for lowest flow rates, as remote version with up to 4 I/Os. Suitable for applications with smallest flow quantities in all industries.
