Field of application
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 compact transmitter Promass A 300 offers high flexibility in terms of operation and system integration: access from one side, remote display, improved connectivity options. 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
