Overview

The InnovaSonic 203 liquid flow meter is optimized for customers still looking for high performance, but needing a lower-cost, less feature-rich option for dedicated clamp-on ultrasonic metering. The 203 digital liquid flow meter optimizes the measurement of water as it flows in HVAC, irrigation and other liquid applications.

Common Applications: 

• Cooling and heating fluid measurements
• Water and wastewater measurements
• Leak detection in piping systems
• Monitoring and controlling of HVAC systems
• Contactless product recognition
• Interface detection
• Automated process control

Product Benefits
