Proline Promass A 200

Summary

Product identification

• Product name: Proline Promass A 200
• Product type: Coriolis flowmeter
• Description: Genuine loop-powered flowmeter for accurate measurement of lowest flow rates. Ideal for continuous process control in demanding applications.

Field of application

The compact Promass A is ideal for continuous process control in 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 cost-effective genuine loop-powered technology and intrinsically safe design (Ex ia), Promass A 200 offers highest operational safety in hazardous areas. Heartbeat Technology enables safe processes.

Suitable for applications with smallest flow quantities in the chemical industry.
