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 ensures 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.
