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.
Measuring principle operates independently of physical fluid properties such as viscosity or density. Suitable for applications with smallest flow quantities in the chemical industry. Genuine loop-powered flowmeter for accurate measurement of lowest flow rates. Suitable for applications with smallest flow quantities in the chemical industry.
