Clamp On BTU Meters
The STUF-300R1B ultrasonic thermal energy meter provides abundant capabilities for accurate thermal energy measurement of a liquid-based thermal energy production / transferring system.
The STUF-300R1B system is consisted of a high performance ultrasonic flowmeter and a pair of standard PT100 temperature sensors. The ultrasonic flowmeter is based on our cutting-edge clamp-on flow measurement technology, which is capable of measuring the flow from outside of a pipe accurately and reliably. Due to the non-intrusive nature of this technology, there is no pipe cutting, no moving parts, no pressure drop, no leaks and no risk of contamination. Besides, the installation is simple and requires no special skills or tools.
The two PT100 sensors, which could be either insertion type or surface-mounting type, are used to measure the temperature of the supply flow and the return flow. The energy consumption rate is then calculated based on the temperature difference and the measured flowrate. A built-in energy totalizer is used to accumulate the amount of energy delivered.
STUF-300R1B is an ideal choice for improving HVAC, energy production and building energy efficiency in terms of heating, cooling ventilation and air-conditioning.
