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 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. Device properties Remote version with up to 4 I/Os Backlit display with touch control and WLAN access Standard cable between sensor and transmitter 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
