Proline Promass A 500
Coriolis flowmeter

The single-tube flowmeter for smallest flow quantities, as remote version with up to 4 I/Os

  • Coriolis flowmeter - Proline Promass A 500 ©Endress+Hauser
  • The Coriolis Flow Measuring Principle

The self-drainable Promass A accurately measures lowest flow rates of liquids and gases, also under high pressure. It enables continuous process control for a wide range of very demanding applications. With its innovative remote transmitter Promass A 500 maximizes installation flexibility and operational safety in demanding environments. Heartbeat Technology ensures compliance and process safety at all times.


  • Highest process safety – self-drainable measuring tube design

  • Fewer process measuring points – multivariable measurement (flow, density, temperature)

  • Space-saving installation – no in/outlet run needs

  • 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

Field of application

  • Measuring principle operates independently of physical fluid properties such as viscosity or density

  • Measuring accurately smallest quantities of liquids and gases for continuous process control.
