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℃)
Benefits

programming of pipe diameter, pipe material, liquid type, and
measurement units.
Principle
TVT(Transit-Time Vortex) technology represents a cutting-edge
approach to ultrasonic flow measurement, combining the principles
of transit-time ultrasonics with the capability to harness the
vortex shedding phenomenon, delivering unparalleled accuracy and
versatility in ultrasonic flow meters. This innovative integration
technology enhances the accuracy, versatility, and performance of
ultrasonic flow meters, making them well-suited for a wide range of
applications across various industries and is a valuable solution
for industries requiring precise flow measurements in varying flow
conditions.
- Enhanced Accuracy in Turbulent Flows:
TVT technology excels in applications where fluid flow conditions
vary between laminar and turbulent. The incorporation of vortex
shedding data enhances accuracy in challenging flow environments.
- Versatility in Fluid Types:
TVT technology is versatile and suitable for a wide range of fluid
types, including liquids with varying viscosities and densities.
