"Field of application
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
enables measurement reliability and compliant verification.
Measuring principle operates independently of physical fluid
properties such as viscosity or density
