ST501-PT100 Ultrasonic Energy Meter
Clamp-on type ultrasonic energy meters for cooling and heating consumption measurement.
Introduction
ST501 is a high-accuracy ultrasonic flow meter with clamp-on transducers measuring big pipe diameter, which is built-in RTD module. When it is equipped with PT100 temperature sensor, ST501 can be upgraded into energy meter used for measuring individual energy consumption in any liquid heating/cooling systems. The meter is supplied complete with flowmeter and temperature sensor, which can makes the system real-time detect the temperature of supply and return pipe.
The energy meter can be widely applied in various applications, like HVAC, cooling tower, data center, energy audit, and building(shipping mall, office, museum, hospital, school, subway etc.). Energy meter, also called thermal energy meter or heat meter, is used to accurately measure heat consumption in heating and cooling facilities so as to reach energy-saving and cost-saving.
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℃)
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.
