Working Principle

The multi-parameter flow meter continuously measures the flow characteristics of the process medium while simultaneously monitoring temperature and pressure. Internal compensation algorithms process these parameters to provide accurate real-time flow measurement and stable output signals.

Integrated electronics calculate:

• Instantaneous flow rate
• Total accumulated flow
• Process temperature
• Pipeline pressure

The measured values are displayed locally and transmitted through analog and digital communication interfaces for industrial control systems.
