ST501-PT100 Ultrasonic Energy Meter
Clamp-on type ultrasonic energy meters for cooling and heating consumption measurement.
Introduction
ST501-PT100 is an upgraded version of ST501, adding heat energy measurement function, so it can detect flow rate and heat energy consumption of the fluid at the same time.
Main Features
• Precise bi-directional and highly dynamic flow measurement with the non-intrusive clamp-on technology.
• High accuracy at fast and slow flow rates, high temperature and zero point stability.
• Water and liquids, tolerant of liquids with small amounts of air bubbles or suspended solids
•Automatic loading of calibration data and transducer detection for a fast and easy set-up, providing precise and long-term stable results.
• Clear and simple menu selections
• Clamp on transducer and insertion transducer versions
•Transducers available for a wide range of inner pipe diameters(25mm~1200mm) and fluid temperatures (0~60℃)
Applications
Widely used in HVAC, industrial, medical, chemical, environmental and other fields.
