10.1 Technical data at a glance
10.1.1 Application
• Measuring the flow rate of fluids in closed piping systems.
• Applications in measuring, control and regulation technology for monitoring
processes.
10.1.2 Function and system design
Measuring principle Prosonic Flow operates on the principle of transit time difference.
Measuring system The measuring system consists of a transmitter and sensors.
