Overview

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 compliance and process safety at all times.

Benefits

  • 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

  • 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

Application

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